IMO there are very few souvenirs worth bringing back, except maybe some wood carvings. Many of the trinkets are made in China, and local made bracelets and necklasses can be bought anywhere in the world. We always bring back dried jerk spice which can be purchased in small bags for a buck or so. Another thing that is good is Sorrel Tea which is only $1.50 a box of 20 bags and can be purchased at the supermarket. Some people might just enjoy having a nice crisp 100J banknote.
