A recent Consumer Reports study comparing grocery prices across Illinois found that two local supermarket chains, Jewel-Osco and Mariano's, offer lower prices on a basket of common grocery items than Walmart. The findings challenge the common perception that Walmart consistently has the lowest prices, especially for shoppers in the Chicago area.

Why it matters

As inflation continues to impact household budgets, the ability to find the most affordable grocery options is crucial for many Illinois families. This study provides valuable data to help consumers make informed decisions about where to shop and potentially save money on their weekly food costs.

The details

The Consumer Reports study looked at the total price of grocery baskets containing packaged goods, produce, and meat at major retailers across six different regions, including the Chicago metro area. While Walmart is often touted as the low-price leader, the analysis found that Jewel-Osco and Mariano's both offered lower overall prices on the comparable basket of items in Illinois.

  • The Consumer Reports study was conducted in early 2026.

The takeaway

This study challenges the long-held assumption that Walmart always has the lowest grocery prices, at least in the Illinois market. For cost-conscious shoppers, it may be worth considering Jewel-Osco or Mariano's as alternative options that could provide greater savings on a typical weekly grocery run.
