Now that you have your Amazon Associates Account created, you can now go in and create your Astore. To do this you've probably received an email with the direct link, however, I'm going to assume you don' t have that. Go to the bottom of Amazon.com and you will see a column for "Make Money with us". If you look in the column you will find a link that says "all". Click it. On the left-hand side there is a link labeled "associates". Click it. You can sign in on this page. You should have an account by now, if not, you can sign up here.
Once you sign in, you will find a menu stretched across the stop. You are looking for the link that says, "aStore". From here you add your store customizing it as you see fit for your site. Remember, Amazon will place a 24 hour cookie on the computer of whomever clicks on your link. That means that even if they go away, if they return and purchase within the next 24 hours, you will receive credit.
Great job!
Now that your site is created, it's time to get it uploaded into WA Hosting(or any other hosting company you have).
