Costco

Costco is a membership-only warehouse retailer running roughly 900 locations worldwide, and it takes a large share of its operating profit from membership fees rather than product margin - renewal rates in the US and Canada sit above 90%. Founded in Seattle in 1983, it is known for holding prices on signature items: the $1.50 hot dog and soda combo has not changed price since 1985, and the $4.99 rotisserie chicken is a deliberate loss leader.
