In the second annual Retailer Price Index (RPI) study, completed by Dunhumby, the following ten stores made the cut of cheapest grocery stores. Out of the 50+ grocery stores included in the survey, the top 10 winners in price are below.
WinCo Foods keeps its costs low by cutting out distributors and intermediaries and buying many goods directly from farms and factories. As a result, WinCo stores are minimalist, with few frills and options compared to larger grocery chains.
Costco has a general rule that no item may be more than 14% over cost. Like other cheaper grocery stores, Costco keeps its prices low through private label brands, such as Kirkland, while also efficiently distributing.
