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 Shopping 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 "Place Order" link at the top of the
page. You will be given the chance to verify your purchase before
proceeding to checkout. 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.
