Costco
“Can Costco's membership model become the financial relationship layer for middle-class American households, using exclusive financial products to deepen loyalty and justify membership renewal?”
Costco is a membership-based warehouse retailer that has progressively layered financial services onto its core retail flywheel. The membership model creates a captive financial relationship — Costco earns on memberships, not margins — enabling it to offer deeply discounted financial products (insurance, credit cards, payment processing) as member benefits. The company has expanded embedded finance gradually: exclusive co-branded credit card (now Citi/Visa), digital wallet (Costco Wallet / Costco Pay), supplier working capital (C2FO dynamic discounting), and most recently BNPL at checkout via Affirm (2025). The strategic thesis is using financial services as a membership value amplifier, not a standalone profit center.
