I’ve had several friends buy through Greentoe without problems. The people who are apt to rate these services are the ones who had problems so usually these ratings are not indicative of the actual percentages of bad results. All anyone has to do is use a service like PayPal to protect themselves. Any legitimate Credit Card will provide the same protection. People here have made nasty comments about Dvor based on ratings but no personal experience with them. Same with CampSaver. I’ve bought through both several times with great results. Some Chicken Littles on the board.
