I am looking for an online e-Commerce/Shopping Cart solution. I want to find a place where I can input my design/code, and the service runs the site for us. I don't want to have to download and try to run a software/database myself. The problem I keep coming across though is that they all require the use of their templates which are hard or not possible to modify. Has anyone out there used a shopping cart system where I can 100% customize everything for the site?
