But if the cambios in Jamaica are giving 85/1, and xe is 89/1, you're losing $4 JMD per dollar you convert, losing roughly 5% of your value.
I guess it beats pulling out a currency calculator every purchase....
Cambios generally give the best rate, especially compared to the airpor. IF you see an xe rate of 89/1 that might be what it would cost to go from Jamaican to USD, not the other way around.
