A limited assortment of grocery store brands offer store-brand products and a few other brand items. A good example is Aldi.

Supercenters offer groceries, produce, meat, and other food departments in addition to non-food items. Examples of supercenters include Target and Walmart.

Club stores are similar to warehouse groceries in that they offer you discounts, and you can buy groceries in bulk. However, you have to be a member to shop. Examples include Costco and Sam's Club.

A gourmet store sells health foods, specialty foods, and nutritional supplements. Since they offer local and organic food that could be imported, you can expect to pay premium prices. Dean & DeLuca is a good example of a gourmet store.

Military commissaries provide service members with the same products they'd find in the U.S., even abroad. These stores are similar to supermarkets, except the United States Defense Commissary Agency runs them.
