Volume isn&#x27;t the only thing in CC realm. Visa, MC, AMEX charge a pass-through rate. If the deal with Starbucks didn&#x27;t push the pass through rate and charged south of 10 basis points, then they&#x27;re not making money but still have to spend money on infrastructure.<p>Companies that act as gateways are not making large chunks of cash so every basis point matter.<p>edit: spelling, structure
