Grenada is truly a nation of entrepreneurs, from retail businesses and processing operations, both with employees, to vendors (about one-third of the population) who personally sell their handicrafts in the markets. Note that bargaining isn't customary either in shops or markets.
Stores in Grenada are generally open weekdays from 8 to 4 or 4:30 and Saturday from 8 to 1; some close from noon to 1 during the week. Most are closed Sunday, although tourist shops usually open if a cruise ship is in port, and some mall stores, particularly supermarkets, are open for longer hours on weekends.
Some unique, locally made goods to look for in gift shops and supermarkets are locally made chocolate bars, nutmeg jam and syrup, spice-scented soaps and body oils, and (no kidding) Nut-Med Pain-Relieving Spray. Grenada's best souvenirs or gifts for friends back home, though, are spice baskets in a variety of shapes and sizes that are filled with cinnamon, nutmeg, mace, bay leaves, cloves, turmeric, and ginger. You can buy them for as little as $5 to $10 in practically every shop, at the open-air produce market at Market Square in St. George's, at vendor stalls along the Esplanade near the port, and at the Vendor's Craft & Spice Market on Grand Anse Beach. Vendors also sell handmade fabric dolls, coral jewelry, seashells, spice necklaces, and hats and baskets handwoven from green palm fronds.
Here's some local terminology you should know. If someone asks if you'd like a "sweetie," you're being offered a candy. When you buy spices, you may be offered "saffron" and "vanilla." The "saffron" is really turmeric, a ground yellow root, rather than the (much more expensive) fragile pistils of crocus flowers; the "vanilla" is extracted from locally grown tonka beans rather than from actual (also much more expensive) vanilla beans. No one is trying to pull the wool over your eyes; these are common local terms. That said, the U.S. Food and Drug Administration warns that "vanilla" extracts made from tonka beans can have toxic effects and may pose a significant health risk for individuals taking certain medications.
