I would greatly appreciate any feedback. I was considering using paypal as a shopping cart on our site. However, there shipping options seem very limited. does anyone know of a similar shopping cart, merchant service that allows you to customize shipping options such as: Customers can pick whether they want to use post office or UPS (next day, 2nd day, ground). I also need the ability to charge the appropriate shipping charges for international orders. Paypal seems to only allow you to set a flat rate based on a dollar amount spent or a percentage. It would be nice if I could charge, x amount for one item, and then a flat rate for additional items (were talking about music cd's.) Appreciate any feedback. thanks in advance.
