Basically, I want to be able to have a link where I can send users to from a non-oscommerce site which automatically adds an item to the oscommerce shopping cart based on its oscommerce ID. Example, when they go to
http://www.mypage.com/oscommerce/add...p?productid=10, it will show the cart with product 10 in it. Willing to pay for the script if its too much work.
