Any international airport that has flights to or from the DR has a money-exchange service in the airport, but be ready to get a haircut - if the tasa in the DR is 33 to 1, you MIGHT get 22 to 1 there. OR, find a local dominicano who has a use for them.
Wow!!!
I would love to buy USD's for 22 pesos.
Where in the US can I exchange my Dominican pesos for dollars?
