Costco Facing Lawsuit Over ‘Fishy’ Advertising Practices

People love shopping at Costco  (COST) – Get Free Report. The membership-based warehouse club has dominated the American Customer Satisfaction Index’s annual retail survey.

The retail giant has topped the survey for six straight years scoring an 81 on a scale that goes to 100, leading its top rival Target (TGT) – Get Free Report and Walmart’s  (WMT) – Get Free Report Sam’s Club, which both scored a 78 while Walmart landed at the bottom of the survey with a 71.

Keeping customers happy is essentially Costco’s business. The company sells memberships and member retention and growth are its two most important metrics.
