Convenience stores usually charge higher prices than conventional grocery stores or supermarkets.[2] But convenience stores have gained market share. This shows consumers are willing to pay more for convenience.[2] Convenience stores order smaller quantities of inventory at higher per-unit prices from wholesalers.[3] However convenience stores make up for this with the convenience by having longer opening hours, serving more locations, and having shorter checkout lines.[3]
