I have a cre loaded 6 pro shopping cart. I want a one page checkout implemented that is similar to Volusion's One Page Checkout: [url removed, login to view]
It must support CCGV (that contribution is already installed, so the one page checkout must support coupons and gift vouchers).
It also must support Purchase Without Account (that contribution is also already installed).
I don't use dynamic shipping, only the table base rates. It also must work with [url removed, login to view] and Paypal for the payment options.
