Founded in 1978 by the Atlantic Richfield Corporation, AMPM is a chain of convenience stores most often attached to ARCO or BP gas stations.
BP acquired Atlantic Richfield in 2000. While many locations have changed the name of the gas stations to BP, some retain the ARCO name and logo. The AMPM name remains the same. Convenience stores are mostly franchises with more than 970 locations found mainly in the Western portion of the US.
A key focus of AMPM is its food program. Stores offer fresh coffee, bakery items, fresh sandwiches and hot foods, such as hot dogs and burritos. AMPM offers up to 24 different soda fountain flavors and a condiment bar so customers can top off their nachos or hot dogs with pickles, onions, cheese, and other items.
Headquarters for the company are located in La Palma, California.
