Check out Pricesmart. If you don't have a friend to go with you who is already a member, you might want to consider joining. You can also save a buck or two on bulk household items. They have a pretty good selection of housewares, bedding, linens, appliances, etc.
If you have a big cooler, take it with you. You'll also find good prices on meats, frozen items and vegetables.
