This look like a promising and simple to use plugin....
When using the Google checkout button the following error happens:
Seen from the merchant Control panel -
"The currency used in the cart must match the currency of the seller account. You supplied a cart with USD and the seller account is associated with GBP."
In the SCABN settings the currency is set to GBP, and it shows across the site.
Also, how do i turn off the Paypal button i don't want it?
