I got a gift card for visa and
I want to shop online so I went to amazon.com
I got the stuff I wanted and I put everything I needed to
but it didn't come through as in I didn't receive what I had paid for
so... I'm thinking I did something wrong =D
and I wood appreciate if someone can tell me just simply how to order something on
Amazon.com

You find what you want and add it to your cart. When ready you place your order for what's in the cart and make payment arrangements.

You can check your order status to see whether the order went through or not.
