I'm going to keep my .com/.org purchases under wraps for now. Sometimes when people know how much you bought a domain name for, there's some psychological response that tells them not to offer much more than that amount. Anyone ever experience that? :D
So, here's my biggest purchase amounts in these obscure extensions.
.ws $15
.st $100 (still have it)
.cc $250 (still have it)
.to $600 (resold for $5,700)
