Excellent point Likkle Sistah! The consistent devaluation of the JA$ is a major problem.
And Livin603, the majority of businesses in Negril and Jamaica are Jamaican owned. For years people thought the Sandals and SuperClubs were foreigned owned.
The vast majority of businesses that take their resources to post the US exchange rate also post the Canadian, Euro and Sterling pound.
And as an FYI, just because a business may have their prices in US$, businesses in Jamaica MUST accept JA$. You will not run into a business that wont accept JA$.
If the transaction is conducted off the island, that is a different story. It surprised me that several non-US airlines show their airfare in the US$ when checking airfare from Jamaica. I expected JA$ rates. What seemed like a great JA$ deal, too good to be true, turned out to be a deal too good to be real... (grin)
Some bars and restaurants here do have a great exchange rate. At a bar on the beach for instance, their sign currently says us$5 equals JA$500 - the two for one drinks are a great deal even at the us$5, be sure to pay in Jamaican $$$ for the best deal... (grin)
But remember, you are on vacation, dont sweat the small stuff! The world is as it is...
