Costco vendor compliance: how chargebacks work
Costco's compliance model is shaped by its depot cross-dock network: freight must arrive exactly on appointment, labeled and palletized so it can flow straight through to clubs. Chargebacks are assessed case-by-case rather than through a published numbered-code system.
