Walmart is no longer the cheapest grocery store: See the full list of major retailers

There was a time when shoppers associated Walmart with being a cheap, one-stop shopping outlet, but a new survey suggests that now, when people look for low-cost food, they look elsewhere.

According to a new Consumer Reports survey, the top retailers for consumers looking for low prices are wholesale bulk grocers Costco and BJ's Wholesale Club.

Costco's prices are reportedly 21.4 percent cheaper, and BJ's Wholesale Club was 21 percent cheaper than Walmart, according to the survey.

Coming in at third place was Lidl, which was rated as 8.5 percent cheaper than Walmart, and Aldi, which was 8.3 percent less expensive than the big box giant.

A Walmart spokesperson told OregonLive that Consumer Reports did not share the details of the survey and thus "would need the complete details of their study to run our own analysis before we could comment — as it may be incorrect."

Even though Walmart no longer reigns as the top low-cost grocer, it's still fairly high on the list. According to the survey results, Walmart was ranked the seventh cheapest grocery store. WinCo and H-E-B took spots four and five on the list.

The survey ranked 35 grocery stores from the cheapest to the most expensive. On the back end of the list — the expensive side — the bottom 10 spots include Harris Teeter, Trader Joe's, Albertsons, Tom Thumb, Big Y, Vons, Marianos, Jewel-Osco, El Rancho and Shaw's.

The most expensive restaurant at spot 35 was Amazon's Whole Foods.

Trader Joe's and Albertsons were found to be 25 percent more expensive than shopping at Walmart, according to the survey. Whole Foods was found to be nearly 40 percent more expensive than a grocery run to Walmart.

The survey was conducted by the New York-based Strategic Resource Group. The group compared the prices of "baskets of commonly purchased items at mainstream grocery chains in six regionally representative cities across the U.S." to compile the data.

The results were all collected across a single 48-hour window to account for potential price fluctuations over time. The final data takes outliers like sale prices and discounts — like those from loyalty cards — into account.
