"4502 E Oak St, Phoenix, AZ 85008" pharmacy staff - unprofessional, thinks customers has no knowledge. I was picking up a prescribed cream, the staff says he needs to check the ingredients are there or not, then says as this is prescribed medication, he has to prepare the cream. Told me to wait for 30 minutes, After 45 minutes, I picked up a readymade cream on which he just put a label that COSTCO is selling that product. He supposed to get an authorization from my insurance company & charged me for the medicine, there was nothing more for him to DO for the premade cream. He should not be in COSTCO as employee, I had never expected this kind of service from Costco staff.

If there was a negative number they would receive that! Their online pharmacy marks up over 350%!! When caught they refuse to refund your money then when they realize that they have to they just lie and don't actually refund your money! Basically they steal it and you are out.!! They claim they refund, bank says they didn't, back and forth. Reality is Costco steals it and you never see it. Will never go to costo again. Treated poorly from the beginning with this matter and when you Pay to be a member they need to at least be honest. Sam's Club is much better!!! Watch your pocket book....they are!!!

Called several times and got hung up on. When I finally got through, the pharmacist mocked how I pronounced the medication names and kept interrupting. I left the call feeling dismissed, embarrassed, and deeply frustrated.

Such a bummer. I used to love my Costco mail order service. Just logged on, selected the meds I needed refilled and done. Those days are long gone as they have moved to a new and improved…database? System? Universe? Now I’ve been trying to get a med refilled for nearly a month (fortunately my doc called in a 30 day Rx to my local CVS because I’m out) and sometimes it looks like it goes through, sometimes it tells me the system will not accept that request, sometimes it doesn’t even offer that Rx as an option. I called and waited on line for literally an hour, spoke to a nice man who said he would get it mailed out. Never a peep or update on it. Still nothing at all. Was just notified they don’t have a credit card on file even though they have for the past few years…? Filled out the info through the link, and it won’t go through. Can’t be updated. This new system is way smarter than I am.

I am extremely disappointed in Costco mail order pharmacy. Call there and you’re on hold forever. No way to email or contact anyone. Just says my prescription was sent to Redmond WA instead of my home address. NO HELP WHATSOEVER. I AM EXTREMELY ANGRY.

I’ve been a loyal customer at Costco Pharmacy for many years, but my recent experience with the pharmacist, Vance, was deeply upsetting. 😞 Due to a sudden policy change, my prescription was withheld without any notice — putting my health in serious danger. Stopping this medication abruptly could have triggered a seizure or other severe medical complications. ⚠️🧠💊
When I brought this up and asked if a courtesy call would have been appropriate, Vance questioned what I was saying and completely dismissed the gravity of the situation. His response was cold, condescending, and showed zero concern for my well-being. 💔 😔 I left feeling shaken, disrespected, and genuinely scared that someone in a position of trust could show such a lack of empathy during a critical moment. 🫤 I truly hope Costco Pharmacy reconsiders how it communicates with and cares for its patients. Lives depend on it. 📞❤️🩹

Went in today to get a prescription renewal on a medication I have been taking for 20+ years. They proceed to tell me they now also offer a generic version that is cheaper. I very clearly and specifically state that the medication is not expensive in the first place and that I do NOT want to switch. I do not want to mess with my dosage or any changes with my medication. I am told not a problem. I get my prescription, get home and they changed my medication to the generic against my wishes. If they do not remedy it I will never use them as a pharmacy again.

I made an appointment for a vaccine through their website. They sent a confirmation email with forms to fill out and requested that I arrive ten minutes early for my 1:15 appointment. There was no one in line for a vaccine ahead of me yet I sat in the chair waiting for a hour for the vaccine that took about 30 seconds. I went up to the counter twice and told them how long I had been waiting and they kept saying that someone would be calling me shortly. I won’t be returning to Costco Pharmacy.

The pharmacist felt she needed to contact my physician's office to question the legitimacy of my prescription because she assumed my physician and I are related. The phone number on the prescription was outdated because contact information had recently changed. The pharmacist made no effort to reach me to ask for an updated phone number. When I came to pick up the prescription, she behaved in a very haughty manner and insinuated that I must be doing something underhanded because of the relationship. I do not mind a pharmacist doublechecking in any way, but to treat me like a criminal was insulting and unprofessional. I will take my business elsewhere.

I've been filling prescriptions at Costco Pharmacy for nearly a year, multiple times per month, for both my family and my cat. Despite my doctor providing clear instructions to fill either the name brand or specific generics due to allergies and medication efficacy, this pharmacy has consistently failed to follow those directions. For the past seven consecutive months, I have received a different generic every single time, despite clear instructions. Generics are not identical, and changes in inactive ingredients can affect how the medication works. Even worse, the pharmacy routinely provides incorrect paperwork—handing out name-brand information instead of the actual generic manufacturer’s details. This is a serious issue, as patients deserve accurate information about the specific medication they are taking.
Two months ago, they filled a prescription for a dog, despite me telling two separate pharmacy employees in person that the medication was not for a dog. When I went to pick it up, they still tried to give me someone else’s prescription. It took me refusing to pay and other customers stepping in before they acknowledged the mistake. Additionally, after undercharging me a couple of months ago, they repeatedly called me to pay the difference. I should not be responsible for correcting their own billing errors.
Most people don’t check the medication paperwork they receive, but they should—because at this pharmacy, it is frequently incorrect. For patients like me with allergies (e.g., FDA Blue #2, which causes cystic acne), ingredient consistency is critical for medication stability and effectiveness. Yet, the pharmacy has repeatedly provided false information. Most recently, I was told they “only carry Northstar” for a particular medication, yet my own lived experience—including my most recent refill—proves that is not true. This is beyond frustration—this is a patient safety issue. If they are this inconsistent with my prescriptions, I worry about what mistakes are happening with others. A medication error could be life-threatening. Costco Pharmacy needs to address these serious concerns immediately. And for the record—I’m not a dog.

I have been a customer of Costco Pharmacy in Eden Prairie for at least 10 years. I have spent thousands of dollars there, my daughter's medication is at least $900 a week. She is severely disabled with a rare brain disease. Today I called Costco to see if my daughter's prescriptions were ready because some were ready, but some needed her Dr. to renew two of her prescriptions. The customer service rep, did not seem to know what was going on with her prescriptions, he said that they would be ready by 2 pm... I explained that I wanted to know if the meds that they had to contact her Dr. about had been renewed. He did not understand what I was talking about. I had to explain it numerous times. I asked if he could transfer me to someone who had more knowledge, such as a manager. He finally said they had been renewed and they would be ready by 2 pm. When I got there they had not been renewed by her Dr. I asked to speak to the manager. I told the Manager "Curt", about my conversation, he said too bad you have to come back.
No apology, did not seem the least bit empathetic, I explained to him I had to hire a babysitter to come here and it would be too much for me to come back. He did not care, not even an apology!! I told him that it's his responsibility as the manager of the pharmacy to train the people to understand their procedures and that he obviously did not do his job in training the customer service rep of the importance of telling me the meds were ready.
The biggest betrayal was the fact that he DID NOT CARE! He did not even say he was sorry, not even once during our conversation. He had NO Customer Service etiquette, whatsoever, not an ounce. And he followed me out of the pharmacy to tell me he would try and resolve it, he said "On a humanitarian basis, I understand where you're coming from in being angry". I was like, "WHAT?? On a humanitarian basis?? What does that mean?"...like he was so arrogant that he could not admit they did anything wrong!! He would not take the blame. He could not say he was sorry!! It was very weird. I think that he had the attitude that it was just a small mistake and like no big deal to him. Needless to say. I will be looking for another pharmacy.

Always gets my right and nasty when you point out an error. I’m glad I was being vigilant. As an animal owner with the same phone number on file.

The Costco Pharmacy in Thornton, CO is the best!! My wife and I had been using CVS inside Target and were very disappointed. We noticed how busy the Costco Pharmacy was each time we shopped there, so we stopped by one day and asked about getting our prescriptions transferred. That’s all it took. They contacted CVS and got everything transferred over.
They are all very friendly and helpful. On our most recent visit, Susie was processing our order and we asked about scheduling a flu vaccine. She said she’d be happy to set up appointments for us, but said that if we had time, we could do it right then. Then Aaron took over and in less than 10 minutes, we had picked up our prescriptions and gotten our flu shots.
They are hyper-focused on customer service. Sometimes the line gets long because it’s such a good pharmacy, but at those times team members appear and get all the registers going. The lines evaporate in no time. We have been impressed by everyone who’s helped us at this Pharmacy, but I haven’t gotten all of their names to include in this review. And we love the text notifications and auto-refills.

I went to the Costco on Huntington Rd, to get a prescription for my 6 month old son. The employee asked me if my son was insured and I said not sure. She checked and he wasn’t. The government does however cover certain prescriptions for children, and his puffer was one such item, but it was suppose to come with the chamber, the associate refused to give me the chamber and said if my son was insured I have to pay for the chamber, even though it was written on my prescription. She also told me to go and purchase it from another pharmacy, because I had left my wallet at home. I felt so disrespected because the item was suppose to come with the puffer and she refused to give me. She also told me she did me a favour by sending my son’s prescription to the government. Not happy and definitely won’t be going back here again.
BUSINESSES need to train employees customer service, something we are truly lacking in society today. Totally disgusted with the way I was treated today, and definitely feel like the pharmacist felt as if she was doing me a favour by giving me the medication for my son that I had a prescription for. I’m definitely not going to recommend my friends or family to the pharmacy because the lack of training some individuals have is really annoying. I know this review might not make a difference, but the associate should know that she needs to do better. I hope it does find a way to get to her, because she needs to become a better person especially if you at a job that’s to assist and help people on a daily basis.

I switched from Shoppers Drug Mart to Costco Pharmacy but it seems every time I go there, there are ERRORS made, whether it's billing, quantities or one-time WRONG MEDICATION. I should know that when they give you a slip with a time on it, it puts pressure on the pharmacists to work fast so naturally errors go up. But the frequency with which I get errors has me concerned whether it's worth it to risk my health over saving a few dollars. IMO, the lack of care and double-checking customer orders isn't worth saving a few dollars.

Costco Wholesale Warehouse is just great! Love them. The Cost-Co Pharmacy is not to be confused with them. The Pharmacy at Cost-co is everything that the warehouse is not. I would call them incompetent but it's actually that they simply just don't care, don't have to. Kind of harsh, right? Consider they regularly are unable to fill a common prescription you may have. If it is an ongoing prescription such as for blood pressure or cholesterol you would think that since they know you're on file and will need it monthly that they would figure into their order so they would have it on hand, you would think wrong. If you try calling them a week prior to needing it to ask they order it they will not consider it, too early to do so you will be told. So you will call the day of only to find they are unable to fill several of your prescriptions but they will happily order some and it should be in by Wednesday.
If you are unlucky enough to have any controlled medicines (i,e, Cancer Patient, Pain etc) you may as well forget it. Don't even mess with Cost-co, you will likely be deceased before they will fill it. As I was once told directly by a Cost-Co rep, and I quote " not mine, don't care ". You have been warned, wish I had seen some of these reviews prior to getting tangled up with them.

I recently called Costco Pharmacy, Duluth venture drive and was very disappointed with the service from Cortney. She repeatedly put me on hold and never got back to me. I was on hold for 1 hour but no one still got back to me, I was disappointed that she was the only one attending the phone. Additionally, she was not polite and came across as very rude. This level of customer service is unacceptable, and I hope it is addressed to improve future interactions.

Every time my doctor has changed dosage for my medication, the staff repeatedly fails to to read the new prescription order. It then will repeatedly get rejected by the insurance due to refill restrictions. I then, have had to spend numerous hours on the phone explaining that it's a dosage change, and painstakingly try to get doctor to resubmit it and Costco to understand it. When all they have to do is actually read the order. This place is the worst.

Went into Costco August 21st 2023, used self check out. I had two separate orders to process. I asked her to scan the toilet paper onto my first bill, she replied with, "What about all your other stuff." I said I was doing two separate orders. She rolled her eyes and kissed her teeth at me. Then after completing my first order, she stood right beside me watching me scan my second order. Once I completed the order an elderly gentleman beside me was having issues with the self check out ask her for help. She rudely replied, "Look at the screen and follow the instructions. You tap the green button", and then said something in her language. So I went over to help him. Then I went to speak to Paul the “manager.” He didn’t seem like he gave a crap and was barely even making eye contact with me. Very poor customer service.

I tried to use a GoodRX coupon at Costco pharmacy in Pooler, GA. The same coupon I had previously used and is advertised by Costco. The young woman helping me said she could not honor the coupon. She was annoyed but I asked to speak to someone else since I had specifically had my Dr. send my script to this pharmacy to use the coupon. After much debate the pharmacist said he would allow me to the use coupon one more time, but not again. Ok, fine. I did tell him it was frustrating that Costco would advertise this price then not honor it. Anyways, I know me and my coupon were a pain, but I thanked him for honoring it this last time.
While I continued to shop at Costco I walked by the pharmacy again and made eye contact w the young lady who originally helped me. She saw me and called me a ** as she walked by. I was flabbergasted! All over a coupon, geez!! I did go and let the pharmacist know I didn’t appreciate being insulted by their employee. The pharmacist informed me he didn’t hear her say that. Ok….But then he quickly added he would address it. I’m not sure if he actually was going to, but definitely won’t be using that pharmacy again.

Don't use Costco's online pharmacy based in California. First, the system doesn't let you have the prescriptions for more than one person per email address. If you have young children you have to set up an account for each person. Second, their website seems to arbitrarily turn off auto refills. And finally, it takes up to two or more weeks to get refills on an existing prescription. Even if you ask for 2-day delivery, it doesn't arrive on time. Ten days and counting currently.

Costco Pharmacy is worst for customer service. It's taken 6 phone calls to get a refill and still not done. First they denied they received the script from doctor.

While Costco Pharmacy offers very low prices for medication it definitely isn't worth the hoops you have to jump through to get a refill. Costco completely messed up one of my prescriptions 3 times and the pharmacist I interacted with in person was one of the most condescending and rude individuals I've ever met. It shouldn't be this hard to get refills of important medications.
All of my prescriptions have been written for a 3 month supply, when I switched from using the in person pharmacy to Costco's online pharmacy they only sent me a one month supply of my medications. This was really inconvenient for me but I figured it would be fine if I just set up auto-refill/auto-delivery. I signed up for auto-refill just fine and double checked that it was turned on in my account. Later in the month I realized that I was running low on my medication but my refill still hadn't been delivered yet so I logged into my account only to find that auto-shipping had somehow been deactivated and my prescription hadn't been refilled. I immediately requested a refill but knew it wouldn't get here in time before I ran out.
The next day I called my local Costco and asked if I could get a 5 day supply of my medication to hold me over until my actual refill arrived, the pharmacist was very kind and said that they would be able to do that and I could come in and pick it up the next day. The next day I rushed over to the pharmacy after work and was met by one of the rudest people I've ever encountered. When I explained that I was there to pick up a prescription she said that there was no prescription ready for me. I reiterated that I had talked to a pharmacist on the phone the day before and she said that my prescription would be ready the next day. The pharmacist was very condescending and said that the doctor has to sent them a script before they can just fill it, which I understand, but in the past whenever a pharmacy has had an issue with one of my scripts they have called my Dr's office and taken care of the issue for me.
When the person I spoke with on the phone said that I could come pick up my script the next day I figured that they would've called my Dr to have a script for a 5 day supply sent over. If they would've told me over the phone that I needed to call my Dr first, I would've been happy to do so even though I'm pretty sure that's their job. I ended up leaving without my important medications and now my health is at risk because of their mistakes. Risking your health is not worth the lower prescription costs, I highly recommend going elsewhere for your prescriptions.
