A recent 'experimental' letter posted ordinary airmail from Puerto Plata Post Office to Dorset, UK took 3 weeks 2 days. No special service or security and it got there in the time frame I expected. That was a letter, I've never sent a package (of important documents) by anything other than Fedex. I give mail to friends returning to UK, already stamped but left unsealed. With tourists whom we don't know, there have been some refusals to take unsealed letters, so I assumed Brits. are getting more suspicious & haven't in years asked anyone whom I don't already know.
My incoming mail from UK using Business Mail takes 3-4 weeks and it always gets here, eventually. Incoming ordinary airmail from UK using Dominican postal system takes 4-5 weeks usually unless rerouted to Dominica (then it's 3 months) & it doesn't always get here, at least not to my P.O. Box in Puerto Plata Post Office :cheeky:. A recent document from UK using International Signed For service out of UK did get here, took 4 weeks.
