A new "Consumer Reports" study found the cheapest place in America for groceries is Costco, where stuff is 21% cheaper than Walmart.  The priciest store is Whole Foods, where stuff costs 40% MORE than at Walmart. "Consumer Reports" did a deep dive to find the cheapest and priciest grocery stores in America.  And both ends of this list make sense.

They looked at 35 different chains, and actually had people go pull prices directly off the shelves.  They used what you'd pay if you had a loyalty card with discounts.

And after all that work, they found that the cheapest place in America to get groceries is . . . yep, Costco.

They compared prices for all the stores to how much you'd pay at Walmart, the largest grocery chain in the U.S. You'll pay an average of 21.4% less at Costco.  Then BJ's Wholesale is a close second.

The five cheapest stores are:  Costco, 21.4% less than Walmart . . . BJ's Wholesale, 21% . . . Lidl, 9% . . . Aldi, 8% . . . and WinCo, 3% less.

The priciest major supermarket is Whole Foods.  Stuff there costs an average of 40% MORE than Walmart prices. (The rest of the bottom five are Shaw's, El Rancho, Jewel-Osco, and Mariano's.)
