As Amazon beefs up its food business and Aldi plots its American takeover, the competition is tighter than ever. But, the biggest names don't necessarily line up with the best savings.
In a January report on the grocery business, customer data company dunnhumby used publicly available financial data and a survey of 7,000 households to analyze customers' perception of which stores offer lower prices than other retailers across the US.
"Despite the wealth of commentary in the news committed to customer needs surrounding convenience, digital and having the most on-trend products, price remains more important to most shoppers even those who have higher than average income," the report states .

13. Sams Club
