It's highly likely that the cigarettes will be cheaper in St Vincent than in the duty-free - they are certainly considerably cheaper in the St Vincent supermarkets than they are at the duty-free stores in Barbados and London.

Here in St Vincent, if you buy a carton of cigarettes such as Dunhill, you will pay around $EC 47 per carton which means $EC 4.70 or $US 1.75 per packet of 20.
