Think of the sorts of things you might want to buy for yourself or for your friends or family. Bird or nature-related items are always very popular, especially those with a Caribbean theme or things that are hard to get at home. Things like the latest (or antique) field guides, natural history books, paintings, photographs, artwork, handicrafts, shade-grown coffee, binoculars and other field equipment, field bags, stamps, handicrafts, t-shirts, scarves, beach wraps, pins, jewelry, CDs, ceramics, carvings, iron work, tote bags, toys, puzzles, bird feeders, bird tours, educational materials, rum, and chocolate all tend to sell well. The most popular items are not always the most expensive ones but the things that catch people's imagination. Be creative!
