I am looking for an ecommerce solution similar to SimpleCart in the fact that it is one page and allows PayPal (or Google Checkout ect.) to handle the heavy lifting.
However, I need something that can calculate shipping costs and deal with in stock/out of stock items. I would really like it if it was at all possible to have a little bit of a CMS backbone that will let someone easily enter the name, description, ect.
Any help would be greatly appreciated. Thanks.
