Thanks TwoWheel.
I looked into getting a certificate of origin for the GTV last fall and it was 40 Euro, which I was willing to pay, but Chase bank wanted $50 to transfer the money which I wasn't willing to pay!
Piaggio provides a couple ways to transfer money to their account - BIC/SWIFT and an international banking account number - but they are Eurocentric. Apparently these methods are cheap and commonly used in Europe (and maybe the rest of the world) but Chase claims they are on a different system and can't transfer money that way.

I emailed Piaggio through that certificate portal asking for other payment options, but they did not respond. It would be much cheaper to have a paypal or credit card option than a 20% discount.
Anyone know how to do this for less? Thanks!
