I know your cart supports a lot of options - but I have been asked to do a site for a company based in Sweden
They have said http://www.epay.eu/epay-payment-solutions/ will work there
Is this compatible with your cart ?
If not can you advise which payment provider in your list will work with a Sweden based company ?
We normally use Sagepay but they don't allow Scandinavian companies to use their services
Hope you can help
