$75 is insane! :vangry:
to get the bus from the airport you have to take a taxi to caribe tours at the bus terminal. 400-500 pesos. then get the next caribe tours bus to sosua (los charamicos) for about 80 pesos. when you get there catch a moto concho for about 20-30 pesos. total 500 to 610 pesos or about $20. it'll take you an hour or so longer than a direct taxi but will save you $50+.
