I am a long-time collector, starting as a boy in London in the 1950's.  My family emigrated in 1956, and I began collecting more seriously in the mid 1980's.  Now that I am retired, I am revisiting my collections and applying all sorts of new rules.  Like selling all my used stamps, and collecting more or less all of some countries 1901 through 1960, and otherwise collecting countries very selectively.

I am currently selling only on StampWants, but I buy from the APS website, on delcampe, eBay, and StampWants, and from various dealer websites.  Of course I prefer to buy here on StampWants, and usually I can find what I am looking for here, but if I cannot find what I am looking for here, then I look elsewhere.
