I use a credit card and I don't get hit with international fees. Your bank is suspect in this case. Also, all the prices are in US currency and IIRC GOG has a server in Texas...so where are the international fees again??
Even if the servers are located in Texas, the billing part of gog.com is outside USA, and a LOT of banks here in USA are changing how their bank cards or even just creditcards, work in relation to overseas transactions.
My bank refused gog.com at first, I had to spend 2 hours on the phone to get it to work... I would hate to think what would happen if I went on a vacation outside USA and my card was declined.
Now my bank has a limit of 20 purchases in 24 hour period, now if only I can get rid of that with a 2 hour phone call I'll be happy, sadly that is an embedded part of their "anti-fraud' messures.
ps, not all of this was directed at you JudasIscariot, just the first part is all :D
edit: wow I DIDNT notice this thread was so old :/ my bad my bad. at least it wasn't me that necro'd it.
