My wife and I are returning to the DR after 18 years since our last visit. On the firt trip we met a gentleman from New York that was originally from the DR. He brought a number of items (pencils, baseball caps, etc.) that he used for barter. He said that the dollar is always welcome, but there were some items that were hard to get in the DR. What he didn't use for barter, he just gave to kids on the beach. Is this still the case? If so, what are some suggested items?
