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.
