I know many of us check and use ebay regularily, so what do you buy? or do you just window shop?
My most recent purchase is a set of pulp magazines from the 50's with the first serialized version of Heinlein's "Door into Summer".
Most of my purchases are books and some bike parts.
Hopefully the vintage mountain bike I am currently "winning" on does not get bid up much more than what it is at now. The bike is a hard to find mid 80's Fat Chance in my size, double rare in Canada.
