I need a shopping cart like [url removed, login to view] that plugs into the page and that I CAN USE OVER AND OVER FOR FUTURE CLIENTS. I want to be able to change shipping and tax options and only have to enter [url removed, login to view] user name and key for automated credit card charging. and also have the option of form to email without automated billing. No OS commerce [url removed, login to view] shopping cart should plug into any existing html site. just like example.
Can be done with powerful admin area and high quality design. I'm familiar with that kind of shopping carts. Can be done as your required.
