My experience in Puerto Plata is that nothing much has made it through the mail system since last August, envelopes, postcards, whatever. Up until then, for the preceding 11 years I used to get mail sent from uk in 10-21 days. My bank statements sent monthly from uk have not arrived since July. Out of 50 Christmas cards which I know were sent from uk, I received 9. I have received postcards from US. S. Africa, Italy etc but not many since last August. Have now moved over to Business Mail, so this isn't a problem but the Puerto Plata post office has been in iffy condition for about 5 months. I'm not even sure it is Puerto Plata's problem, since I have a friend who works there & all the sacks are regularly tipped on to floor when I visit & staff search like crazy. I think the stuff is not making it out of Santo Domingo, since that is where it goes first.
So sorry, JC171, I am not optimistic on this one.
