As the owner of the store, you are in charge of carrying items to customers. Each new customer will ask an item from your store. You'll take the item to them, and earn money! With the money, you can expand your store and purchase new deliveries. As you do so, even more customers will come and ask for items. So you'll have to keep up with them in a hurry! Beware, if you do not make it in time, they'll get angry and leave :) Have fun!!
