In the past five years, American grocery costs have soared.
In 2022, prices for food prepared at home jumped by a historic 11.8% from the year before, according to the Bureau of Labor Statistics’ consumer price index. While prices didn’t drop in 2025, the rate of inflation for groceries has, for the most part, slowed. In July, costs for groceries were 2.2% higher than the prior year.
Nonprofit Consumers’ Checkbook’s latest evaluations of Twin Cities-area grocery stores found most shoppers can save by shopping low-cost stores. Checkbook researchers shopped stores using an 150-item list to compare prices. To evaluate stores on quality of products and service, Checkbook surveyed its members. Here are the findings:
Aldi offers huge savings.
The Germany-based discounter focuses on low costs, and the survey found Aldi quite inexpensive: Based on the shopping list, Aldi’s prices were 41% lower than the all-store average. Aldi’s per-unit prices were even lower than Costco and Sam’s Club.
Aldi’s smaller-format stores partly explain the savings, since the company has much lower overhead costs than conventional supermarkets.
Aldi also benefits from different expectations. Shoppers at Cub, Hy-Vee, Walmart, etc., expect to always find their favorite brands on the shelves. Aldi carries mostly house brands, not national-brand products. Aldi’s shoppers trade that quirkiness for comparable very low-priced products
Other standouts: Walmart and Target
Walmart offered prices about 21% lower than the average at all other stores Checkbook surveyed. Minneapolis-based Target had prices about 13% lower than the all-store average.
For a family that spends $300 per week at the supermarket, a 21% price difference totals savings of $3,276 per year; a 13% price difference totals $2,028 a year.
