Marketplaces by types of participants: C2C, B2C and B2B

Customers can order groceries through the InstaCart app or website and the order is delivered by a personal shopper. Customers can pay with Android Pay or Apple Pay. Initially, InstaCart personal shoppers would simply go to a store and purchase the ordered items at a retail price and then add the delivery fee plus a 10 to 20 percent markup. ................
