How Warehouse Clubs Actually Make Money (It's Not the Groceries)

How do warehouse clubs actually make money if the groceries sell at almost cost? This story puts you inside a warehouse club for one Saturday, from a camera flash at the membership desk and a $65 card still warm in your hand, to free samples, bulk paper towels, a $4.99 rotisserie chicken at the back wall, a $1.50 hot dog combo, and a fourteen-car line for cheap gas. You keep a running total in pencil against a $150 grocery budget, and the receipt says $268.47. You learn why a warehouse club carries fewer than 4,000 items, why the Executive membership only pays off above $3,250 a year, and why the gas station sits in the parking lot. Then the club's own annual report shows where the money really comes from: membership fees of $5.9 billion, about half of its $11.7 billion operating profit. By the end you'll understand the warehouse club business model, how membership fees and bulk buying really work, whether a warehouse club membership is worth it for you, and six rules to check before you renew.
