Just opened this summer - is a small market "Lulu's" just past Grande Caribe that carries most staples you would need (also great prices) - it is run by the same people that run AJi's restaurant (which is also excellent).
Mata Grande grocery farther up north (close to RoJo) is another handy little grocery that sells a variety of goods and produce that you might need in a hurry.
Both of these little grocery markets are owned / operated by super nice and helpful people (I am sure they will order anything you might need for you)!
