A low-margin grocery store offering reduced variety, lower service levels, minimal decor, and a streamlined merchandising presentation, along with aggressive pricing. Generally, warehouse stores don't offer specialty departments, e.g., Xtra.
A warehouse store is a retail location with a limited variety of merchandise sold in bulk at a discount to customers. This type of store is also referred to as a "Big Box" or "Price-Impact" store because of the spartan, warehouse style of the interior and the low prices. These stores tend to feature black text on a yellow background in marketing and in decor.
