Costco
Costco stands out for industry-best pricing transparency (no fake sales, no inflated strikethroughs, no dynamic pricing) and a risk-free lifetime return guarantee on most items. The tradeoff is no competitor price matching and required paid membership to shop. Trust in Costco's everyday low prices is built into the business model.
