Membership and Warehouse Clubs
Costco sells most of its goods at or near cost and makes almost all of its profit from the $65 you pay just to walk in the door. Markups are capped around 14% on most items, half what normal grocery runs, which should make Costco a terrible business. Instead it is one of the most profitable retailers in the world, because the merchandise is basically a break-even lure for the membership. In fiscal 2023 membership fees totaled roughly $4.6 billion, nearly pure margin with no cost of goods and no spoilage, and renewal rates run above 90%. Amazon Prime runs the identical architecture: the annual fee buys commitment, and commitment drives spend.
For founders and operators, the temptation is to copy the fee and assume the lock-in follows. It does not. The fee only renews itself when the perceived savings make paying feel automatic, and the underlying product has to be good enough to pull people back through the door again and again. The high-margin fee can subsidize a better experience, but it will not rescue a mediocre one. The precise conditions that make a membership renew on autopilot, and where it quietly collapses, are what the app holds back.
Frequently asked questions
What is the membership and warehouse club model and how does it work?
The membership model sells goods at or near cost and makes its profit from a recurring membership fee customers pay just to gain access. Because the merchandise is a near-break-even lure, the fee becomes nearly pure margin with no cost of goods and no spoilage. The fee only renews when members feel the savings make paying automatic.
What are real examples of the membership model?
Costco caps markups around 14% and makes almost all its profit from the membership fee; in fiscal 2023 membership fees totaled roughly $4.6 billion with renewal rates above 90%. Amazon Prime runs the identical architecture, where the annual fee buys commitment and commitment drives spend. In both, the product is a lure and the fee is the profit.
What are the risks of the membership model?
The temptation is to copy the fee and assume the lock-in follows, but it does not. The fee only renews when the perceived savings make paying feel automatic, and the underlying experience has to be good enough to pull people back through the door again and again. A high-margin fee can subsidize a better experience but will not rescue a mediocre one.
What can founders learn from the membership model?
Founders should make sure the savings or value behind the fee feel so obvious that renewal is automatic, and use the high-margin fee to fund an experience that keeps people coming back. The fee is not a shortcut; the underlying product still has to earn the renewal. CaseBook helps you decide whether this model fits your business, with an AI coach that reads your answer.
