The reason I brought up about prosecuting the sellers is I have seen people on ebay say "these are my pins from 1962" or whatever. Not only would I like a sister or brother who would do that prosecuted, I'd like them drummed out of the fraternity/sorority because they have no idea what it means.

I realize a lot of the people who buy these at estate sales have no clue, even though they should. What's next, selling diplomas?
As far as selling the sweatshirts, keychains, etc....that to me really isn't different than the college's Greek store selling them. I mean, it's not like I had to show my member ID to buy something in the Greek store. I guess if you have the world's crappiest greek store ever at your college, it could be convenient, although the shipping charges are probably hideous. To me the best way to find paraphernalia if you don't have easy access is to contact your other chapters.
