Fed Mart was founded by Sol Price in San Diego as a government employees only membership store, becoming a Discount Store with groceries by the 1960s. In the 70s Price sold Fed Mart to a German retailer (who by the 80s ran it out of business) and started Price Club.

FedMart
FedMart started off as a membership-only store for jewelry, furniture, and liquor. However, it expanded to offer groceries and other items. In fact, it was the first store of its kind to offer an in-store pharmacy, which is a hallmark of stores like Costco today. It opened in the 1950s and went out of business about three decades later.
