Payment cart for UK?

[Under pressure]

Hi,
I'm thinking about using Paypal express on a new zencart site. Does anyone know if it works with Royal mail shipping?

I have tried Google checkout on the site but could not get it working, and having read lots of posts it seems it won't work with Royal mail shipping.

What is is good payment cart for UK use?

Cheers

Shipping and Payment are separate issues. Payment modules are not dependant on shipping modules.

What is important is that the ORDER TOTAL (in which shipping plays a part) is correct, as that is the value that is sent to the payment gateway.
