Bear, I saw your reply and understood. No, US merchants do not charge in any other currency but US$, but they also don't accept anything but US$, cash or credit. Belize accepts both their own and US$, so it was worth asking. From previous experience, St. Kitts for example, most of the merchants accepted $US and would charge credit cards in US$ (their currency is the East Caribbean dollar). I believe Anguilla did the same but don't quote me on that.

Absolutely Dana, always worth a question. Maybe they were using an Int'l credit card merchant account funded in dollars. They might be less expensive with fewer bank regulations in the British West Caribbean than Bazeeze. You can get an Int'l card account in Bleize that is funded and uses USD here in Belize but they cost an arm and a leg and the credit issues are ridiculous.
Ah Dana! The good old $$BeeWee...we were on St Kitts & Nevis like 30 years ago, fabulous place, Brimstone Hill, I could have wandered that fort for days; stayed at the OTI Ocean Terrace Inn (Golden Rock on nevis). No casino (on either island at that point)the friendliest people, went back again about 5 years after that and the changes had already started.
We use a Chase Sapphire VISA, Great card. Hell can you belive that I actually complimented a credt card company, sheesh I must be gettign senile...
