Yeah, those "charity/help out a board member with expenses/etc." ones fly under the radar, and I remember Arch making a similar comment regarding charity auctions when someone (Comicwiz?) asked him about it.
But that doesn't mean it's cool for personal gain, or that the board and CGC won't come down hard on profit-mongering auctioneers who simply want to transform this into EBay.
profit-mongering auctioneers
So someone posting a book with an Ask Price of $X, let's say for sake of argument at GPA-HI asking price, is not out to make a nice (hefty?) profit and someone who would be happy to risk a book going for 12-cents or some fraction of value is a "profit-mongering auctioneer"??? huh???
You profit monger you! That 12 cent opening bid might make you a millionaire
