 Best cart or button with postage option?
Hi,
I'm based in Australia and I want to sell my tees over the net.
I was going to use a system where the customer places an order via an HTML form, I review th order and post the customer an invoice (including postage), and the customer pays via PayPal. This would work, but the process seems a little drawn-out, and I'm worried it may turn people away.
Alternatively I could use a PayPal 'Buy Now' button, but that wouldn't allow me to charge different postage rates for international customers (without some major changes to my otherwise simple website).
I see Google has a checkout service, which looks great, but it's onl;y available to the US and the UK.
Are there any other shopping carts or buttons, free ones preferably, that are simple to set up and allow me to charge postage? |
