You can only buy things that start with the initial letter of your first name, eg Sam can buy sadines, soup, shampoo etc

The way I used to play it was that each person took it in turns using the alphabet. I bought an apple, next person bought an apple and a bandana, next was an apple, a bandana and a cow etc....
