They dont exist.. TLD and the Tricom card all about 6.5 pesos per minute thats about 40 US cents. And they are the cheapest ones. And you can get those in supermarkets and pharmacies. Compare that with the calling cards from the States to the DR where most are less than 10 cents the minute. This is all because of the monopoly of Codetel. Which is in the process of being broken. Much better prices from the DR to the States will be here within the year.
