Unless the trade war you reference is somehow resolved (fyi that war started decades ago, Trump is just now defending) then I surmise you will likely have to use the DR postal system and see how it goes.I don`t want it free, but I don`t want to be a victim of the trade war that Trump started if I don`t need to.
Understand that the parcels you reference are likely shipped via air by China or Hong Kong Post and delivered to the DR. Since most imported China goods arrive via container taking weeks/months to arrive, the goods you speak about would likely come when a plane load of goods is ready to come to the DR (however long that takes to fill).........and you would then be at the mercy of the dysfunctional DR postal system IMPOSDOM.
Good luck in your quest.
