I'm a little amazed at the the original poster. Should I use a card that charges a transaction fee, or a card that doesn't?!
I got a Cap 1 card years ago, specifically for Belize b/c it didn't hit me the 3%. Charges in Belize always in BZ$, they, the CC co, adjust based on that days market(it is not 2 to 1 on your cc)
