Trader Joe's is 24.6% more expensive than Walmart, a new Consumer Reports study has found, while Aldi and Costco rank among the cheapest grocery stores in the US. The report, which compared prices at dozens of retailers across six cities in late summer 2025, used Walmart as its baseline to highlight where shoppers can find the best deals.
Withfood prices still high as of March 2026, the findings come as welcome news for budget-conscious Americans. Warehouse clubs dominate the lower end of the scale, hardly a surprise given their bulk-buy model.
According to the study, Costco Wholesale tops the list, with prices 21.4% lower than Walmart. BJ's Wholesale Club follows closely at 21% lower. Lidl is 8.5% cheaper, Aldi 8.3% cheaper, WinCo 3.3% cheaper, and H-E-B just 0.2% cheaper.
These figures are national averages, but regional differences exist. For instance,Costcois 37% cheaper in Boston but only 17% in Virginia Beach. Discount chains like Lidl and Aldi, with their European-style efficiency, offer consistent savings on essentials.
WinCo's no-frills model requires customers to bag their own groceries and limits payments to cash or debit, cutting operational overheads. H-E-B gains an edge through regional sourcing and deep community ties, which help negotiate better supplier deals.
In a recent price check,Aldi'sraspberries cost $2.99 (£2.20), compared to $7.99 (£5.90) at Trader Joe's. Organic milk at Aldi is $4.25 (£3.20), while Trader Joe's charges $5.99 (£4.50).
On the flip side, Whole Foods is the priciest, 39.7% more expensive than Walmart. Shaw's follows at 31.9%, El Rancho at 30.1%, and Jewel-Osco at 29.7%. Trader Joe's, despite its cult following for unique items, lands at 24.6% more expensive. This might raise eyebrows among fans who see it as a budget option.
Other notables include Albertsons at 24.8% and Vons at 26.6%. The study notes thatprices vary due to factors like rent, wages, and competition.
Higher costs often arise from elevated minimum wage requirements, steeper commercial rents and property taxes, plus longer distances from distribution centres, which inflate logistics expenses. In wealthier cities, retailers sometimes test higher pricing thresholds, and areas with fewer competitors enable sustained markups without pushback.
'The best environment for consumers is one where a healthy retail mix keeps pricing competitive and selections robust,' said Brian Vines, deputy editor atConsumer Reports. Regional variations can be stark; Whole Foods is 57% more in Virginia Beach.
