For such a country so heavily tuned to tourism, Jamaica is a slightly disappointing shopping destination. Decent locally made handicrafts are too often the exception rather than the rule.
If you hunt around it is possible to come back with some good souvenirs. Jamaica's art scene can throw up some unexpected gems, and you'll never go wrong with Usain Bolt athletics wear in the green, gold and black of the flag. Vinyl fans will love crate-digging for reggae records in Kingston.
One area where Jamaica does excel is in souvenirs you can consume. Leave extra space in your luggage for Blue Mountain coffee and some of the best rum in the Caribbean.
