After my very, very high charge by Fedex experience to send a letter at rd$ 3500 I decided to send my next letter via Imposdom's registered/express service. I posted it in Las Terrenas on the 30-sept-14 at a cost of rd$ 150, it arrived at it's destination Toronto on the 17-oct-14, 2 weeks and 4days later. I consider that not too bad at all so all my future mail will go the same way. I just thought you'd like to know of a RD service that works OK.
