I use a "fair price + 20%" rule. I have been around Jamaica long enough to know what a fair price is for most trips. I usually negotiate for a fair price and then add my 20% brawta. This way, if I feel a likkle overcharged, the brawta is less and the occasional under fair price driver gets more brawta. In either occurrence, both my driver and I feel we are getting a good deal.
