Since you're not American TT...I don't think you'll be worrying too much about finding a lot of American foods...though they are in abundance here along with many Common Wealth grocery items that you'll be familiar with.

The three largest grocery stores here in Negril include...Hi Lo, Value Master & Quality Traders....these are located downtown, all within minutes of the round about.

In the West End, at the end of Seastar Lane is Wise Choice...a small but varied shop. While you're staying on the beach...you'll be close enough to walk to Value Master.
