I have a US credit card but my mailing address is in France. TT did not accept this address.
Soooo
on the personal info page I used my foreign address (MAILING aka Physical address)
when I went to pay I contacted my credit card company. they have two sorts of addresses on file MAILING / PHYSICAL as well as BILLING.
I called them and changed the BILLING adresse to my cousin's address in the states. I waited several days for the change to become effective. Then on the file page, I used my us card with her address. I DID NOT check the box: use mailing address as billing address.
AMAZING - it went through immediately.
note that since the mailing address is where mail goes to, if not to email, than my cousin will not be bothered.
good luck
