Wow, I can't believe how thickheaded some people on this thread are. Sean isn't charging more than cover price of these books.. Its a bloody auction! He will get what the market will bear. If people are willing to pay more than cover price, its because they either want to help out a man and his cat, or they want an autographed book or a custom feat.
And the comments about Sean getting a day job are just ludicrous. Being a game designer for a major company like WotC pays quite poorly, in fact. Doing freelance stuff is boom and bust, which is why Sean has a day job working for Black Isle.
Its amazing to me that people here are mocking the altruism shown by our own community members.
On a more positive note, good luck with the auction, Sean. And I hope your cat gets well soon!
