Grocery prices fell in August


Coffee drinkers have benefitted the most

Inflation appears to be cooling, at least it's declining at the supermarket.

The August ConsumerAffairs-Datasembly Shopping Cart Index for 25 commonly purchased grocery items is $152.7, down 1.2% from July’s index. Year-over-year, prices are up 2.1%.

Among the 25 items in the shopping cart, six went up in price, seven went down and 12 remained the same as in July.

Among items that were more expensive last month, peanut butter was 18 cents more, bacon increased 11 cents and the price of cookies increased by 10 cents.

The plunging price of coffee was responsible for most of last month’s decline in the index. The price of 12 oz. of whole-bean coffee fell from $15.46 in July to $13.76 in August. A dozen organic eggs were 17 cents cheaper last month.

Datassembly, which tracks supermarket prices in real time, reports that over the last three months, egg prices have declined the most while meat and meal alternative prices have risen the most.
