Make sure the buying process makes sense. At a book site the other day I wanted to add a couple of items to a wish list to keep track of them but was faced with having to complete a full registration -- including credit card info -- before deciding to buy. I quickly left.
So, go through the process yourself and see if there are any problem areas from a visitor's point of view.
