Sam’s Club, which is owned and operated by Walmart, sells its own gasoline brand, so the brand name is Sam’s Club. The gasoline sold at Walmart gas stations is Murphy brand. In certain instances, a Sam’s Club warehouse may sell Murphy gasoline or vice versa.
Sam’s Club strives to offer customers the lowest prices possible. Sam’s Club could theoretically save customers money by not selling a major gasoline brand. Those who wish to save money at Sam’s Club gas stations must pay for a Sam’s Club membership.
