C/SCAPE noted that only 18% of the items offered in a convenience store account for 80% of total profits. Items like cigarettes, candy and soft drinks are big moneymakers, but other items like magazines are losing money as a category. By eliminating costly, underperforming items and streamlining categories, stores could run more profitably and give convenience stores a greater competitive edge against other formats.
Delivery costs for convenience stores are much higher than those for supermarkets. On average, convenience stores' delivery costs per cubic foot are five times greater than costs for an average supermarket.
