Contrast that with bidding on Evil Editor to edit your book in the next few weeks. For starters, you can deduct EE as a charitable contribution rather than a business expense, so you don't have to have any writing income. And you get edited by the world's most famous editor, not some ESL-heroin-addict-scam-artist in Ivory Coast.
Even if you don't have a completed book, you should be bidding on this just to keep some billionaire for whom $3500 is pocket change from getting a bargain. You know that no matter how high you go he'll outbid you, but for one brief moment you'll be a thorn in his side. It's human nature not to want billionaires to get great deals. This is your chance to stick it to one.
