Hi Wayne!
I have been using a Mastercard to pay for your merchandise in the US, and this has worked OK... Using an Eurpean bank account may be easier, but I don't know for sure. In Europe, you need a special code for payments between countries, this code is for the specific banks, and it can be difficult to get to this information sometimes. That may have been your problem.
By using VISA or Mastercard I have had no problems either buying parts for my (now sold) KTM super enduro from Germany and Austria, or when ordering tuning parts from England for my turbo'ed Volvo.
You can check out e-bay, they have a special PAY-PAL system that might be some kind of starting point for you?

Anyway, many thanks for a great forum and web-shop...
Ole
