To get from the Airport to the city cheaply, here is Suggestion #1.
Suggestion #2 for getting from the Airport to the City cheaply. Get to the road Las Palomas which runs through Licey, either by walking a bit over 5km, or 1 hour at a moderate pace with baggage or bargaining with some mototaxi or taxi at the airport as per the first suggestion, go a little out of the airport to get cheaper taxis. From Licey there are regular gua-guas westbound to Santiago, which shouldn't cost you more than 25 pesos.
