I just discovered the "product list" section at the top of the "shopping cart" page. I have never had a part number come back as a good number, therefore I was not aware that there was such a list. The list is very helpful but rather hard to find. It seems that the "shopping cart" should be the "parts lobby" or main page, or there should be a link to the product list. Just a thought. I would not go to the shopping cart unless I was ready to buy. Does any of this make sense?
