Sam's Club (Walmart)

Sam's Club offers genuine competition to #1 Costco at a 23% lower membership fee ($50 vs. $65). Its Scan & Go app is the most frictionless bulk shopping experience: members can scan items with their phone and skip checkout entirely, saving an average of 7 minutes per visit. The Member's Mark private label wins 85% of taste tests against premium branded alternatives, making it a bargain on quality too.
