Costco has an unusually strong relationship with its customers.
Since the people who shop in its stores are members, there’s a bond between them and the retailer.
Customers can easily understand Costco’s (COST) – Get Free Report business model. They pay $60 for a basic membership or $120 for an Executive membership (which comes with 2% cash back up to $1,000). And in return, the retailer promises to deliver the best possible prices.
