I'd just try and add such a transfer request to the order, then hope for the best. There may still be some snags, but at least GDC would then not return CC payments by accident. Being able to receive credit card payments tends to be difficult, and I would assume Neo900 UG doesn't have that capability, at least not now. Since refunded CC payments could therefore be messy to re-donate, especially from outside the EU, I think it's worth trying to avoid such detours. - Werner
