To its customers, Costco (COST) makes a pretty straightforward offer.
Access to the chain's warehouse "clubs" costs $60 for basic access or $120 for premium access.
The incredibly cheap pricing that members receive in return for their membership fee.
The products at Costco are really just placed on pallets, and the stores are warehouses, not merely businesses that go by that name.
There is a little variety of goods, but that is also intentional.
In order to negotiate the best pricing with its suppliers, the chain often restricts customer options.
