We have an existing services site that we need to add a simple shopping cart to in order to support 5 to 7 services that can be ordered and paid for online. Instead of “Categories” of products we just need a list of those 7 "Services". After selection by the client and successful payment has been completed, we will need a call made to one of our site pages with the product purchased and the collected consumer information. Please note that links to service description and information pages will often be an html page (not part of oscommerce).
