When you purchase edibles or coffees, check the dates! In GC, we went into a very nice store with lots of outdated Rum Cakes. Jamaica (mo-bay) had the famous Jablum coffee, also outdated in some stores.
If you're a coffee drinker, don't waist your time on the smaller sample bags of coffee. It's sooooooooo good we're going to order more online! We're hooked now!
We found Cozumel to be the best shopping for jewlery. A Tanzanite ring for $350 was purchased for $215!
