When do grocery stores get deliveries?
Delivery schedules vary wildly. Some vendors like Coca-Cola or Frito-Lay may be at a big store every day to restock and other commodities may only be ordered very infrequently (spices are usually considered the slowest mover in the store). Pulling up random egg vendors from the computer suggests that one delivery a week is the most common schedule. Weekly deliveries are usually Monday or Friday. The reason for this is that grocers sell most of their product on the weekend. You’ll have to ask your specific store to be sure.
