Sam's Club is achieving market synergy by combining its retail warehouse store with an adjacent gas station. This is because customers who visit the store for shopping may also fill up their cars at the gas station, thereby increasing sales for both the store and the gas station. It also helps attract customers who may not have visited the store otherwise.
