Since every item is one of a kind, we do everything we can to avoid duplicate orders. When you bring up a page of covers by using a link from the index page, the program only shows you covers that are available at the moment of your request. But two people could be looking at the same page at the same time! By the time you click on a cover on that page, somebody else may have already added the same cover to their shopping cart.

You will receive this message when:

• somebody added the same cover to their shopping cart just before you did **,
• you clicked on the same item twice yourself (check your shopping cart)
