If that's the case, that he's intending to mail some money over, he can send
US dollars, let them change it over there. That might be more convenient.
But sending money except for a few bucks is dicey.
Another option might be a prepaid AMEX Bluebird card or similar. I haven't
use that one in Europe, but credit and debit cards generally work
for purchases or at ATMs. He could check. The AMEX Bluebird you can buy
and load up at Walmart. There is no monthly fee, I think the other
terms are pretty good too
and the exchange rate is probably as good as or better than what you'd get
at some currency exchange shop. Just load it with US dollars, they take
care of the conversion.
