When you first enter the shop, you are assigned a shopping cart that holds your purchases. Whenever you
see an item that you want to purchase, you can add it to your cart by entering the number of items to add and clicking on the "Add" button for that item. The program will then show you the contents of your shopping cart, including the item(s) that you just added.
At any time, you can view or change the contents of your cart by clicking on the "View Cart" link at the top of the page. You can remove items from your cart by simply setting the quantity to zero and updating your cart.
When you have finished collecting items to purchase, you can click on the "Checkout" link. If the shop owner accepts orders by postal mail, you will be given a chance to print an invoice to mail in. Otherwise, your order will be sent to a secure webserver to collect your payment and shipping information.
