Costco's Secret: Why Low Prices Build Lasting Trust
31 May
Summary
- Former CEO resisted a small 3% price hike to maintain brand identity.
- Costco caps profit margins, relying on membership fees for revenue.
- Over 92% of U.S. and Canadian members renew their Costco memberships.

Former Costco CEO Jim Sinegal's resistance to a seemingly minor 3% price increase highlights the company's commitment to maintaining its low-price leader image. He cautioned that such a move, while potentially boosting profits, could lead to a cycle of further increases, ultimately betraying customer trust and the brand's core identity.
This customer-centric approach explains Costco's remarkable loyalty, with U.S. and Canadian renewal rates exceeding 92%. Instead of maximizing per-item profit, Costco caps its margins at approximately 14% for national brands and 15% for its Kirkland Signature products. The company's primary revenue stream comes from annual membership fees, enabling them to offer competitive pricing consistently.
This strategy has allowed Costco to keep popular items, like its $1.50 hot dog and soda combo, at the same price for decades, defying inflationary pressures. This steadfast value proposition builds significant trust, a harder-to-quantify asset than immediate profit gains, reinforcing why shoppers remain loyal even as prices rise elsewhere.
