$1.00 spent in the aisleskept ≈ 2¢
Costco sold $297 billion of merchandise in fiscal 2026 and kept roughly two cents of every dollar.
So how did it earn $9.2 billion? A $65 card, a supplier float most shoppers never see,

Delta's operating profit, 2025 · $5.8B
In 2025 Delta took in $63.4 billion and kept $5.8 billion as operating profit. That same year, American Express
paid it $8.2 billion. That payment isn't profit, but since 2020 the cash Delta gets for selling miles has been larger
than its operating income every single year.
