Belize Bank is the only bank (in Belize) processing AMEX. WHen Scotia Bank was doing the processing it would take weeks to get paid, but now that BB is doing it, its only a day or two before it shows up in your account. If you are in San Pedro or on the mainland, you have the ease of a BB branch at your doorstep. (no this is not an ad for Belize Bank) Here on Caye Caulker we have no Belize Bank office so have to go to the city for any issues regarding AMEX. I have an AMEX p.o.s machine available at the store, but its not widely used. AMEX charges comprise less than 10% of our credit card sales. Very few businesses on Caye Caulker offer AMEX because of having to bank in Belize City.
