I've been buying individual plate blocks and booklets (1940's-80's) since I started collecting a month ago, and what someone said earlier is absolutely correct, I know I have been overpaying, even though I try to look for the best stamps at the lowest price. I have been able to get a few stamps at a slight premium over face plus shipping, but most of what I have purchased is many multiples of face. I have looked at many of the
ebay listings for larger collections and lots, and there are MUCH better deals when buying in quantity, but a lot of the stuff in those lots are stamps I'm not interested in, so what am I gaining? I suppose I could buy a large lot, pull out what I want, and flip the undesirable stuff. Is that what others here do?
