Grocery prices fell slightly in December


The ConsumerAffairs Datasembly Shopping Cart Index was lower than in November

There was good news for grocery shoppers in December. The cost of groceries, as measured by the ConsumerAffairs Datasembly Shopping Cart Index, declined from November but remains above the December 2022 level.

The index tracks price movements of 25 commonly-purchased grocery products, including both food and non-food items. In December 2022, the 25 items cost $155.34. 

In December 2023, the index totaled $156.98, down from $157.19 the month before, a decline of less than 1%.

The December index would have been significantly lower if not for one item -- a 14.3 oz. package of cookies. The sweets rose in price from $5.67 in November to $7.04 in December, a jaw-dropping 24% increase. The price of that package of cookies is up 53% over December 2022.

Otherwise, price movements were fairly tame. The price of paper towels declined 1% from November to December.

Coffee prices continue to fall. A 12 oz. bag of whole-bean coffee cost $12.91 last month, nearly 2% less than the month before.
