Hi I have this siutation going on. For my website we sell hours for cleaning services. So I do not need a shopping cart where people browse products, add to shopping cart, and then check out at a later time. I need an inpage checkout system that lists the hour packages and has a field to imput a discount code and at the bottom of the page it will tell the total and the client can checkout from there. I need a free system like prestashop or something. Please advice how to do this. Thanks!!
