Thanks, any idea how much a 12 pack of presidente costs and perhaps a bottle of Patron and Absolute vodka or a 5 pound bag of ice or a 12 pack of 7up?
You may save a little if you buy a plastic case ("guacal") and pay for the bottles of the 12oz President the first time (President bottles are recyclable). At Janet's supermarket in Cabarete, the 24 case will cost you RD$880. That works if you're staying for a long time. Aboslute is around between RD$700-800. Ice comes in a large bag which is standard; I've never checked the weight or seen larger or smaller bags (RD$30 at Janet's). Cheaper beer which doesn't require you to buy the plastic case and bottles, and also brewed by President, is Bohemia. You can buy a 24 case in a box. I don't recall the price now but it is less than the 880 that I pay for Presidente.
Neither Playero nor Janet nor any large grocery store has "gringo" prices. We all pay the same price. Sorry to quote Janet's prices but that's where I buy more often; Playero is more expensive than Janet's.
There's a place in Sosua Abajo, an Association (no membership required), where I used to buy and has very good prices. I can't remember exactly the name but I'm sure that one of the other members will. Otherwise, try the Supermercado Sosua. They have better prices than Playero.
