But, most often collectors sell their stamps once.
Many collectors become very good buyers.
They spend significant time, effort and expense in the process of acquiring stamps for their collections. Unfortunately, when it comes time to sell their stamps, they are totally bewildered with the process. How and where to sell your stamps is an extremely important part of the collecting process. Often many collectors make the mistake of not selling their stamps at all - while they are alive. They leave the process of disposition to their family or friends.
