Alright, I suggest everyone who wants to play agrees to Paypal Spoo five bucks. When the auction closes, the closest estimate wins the total amount in cash or LuxeSwap credit (whichever's easiest for Spoo). Spoo gets a 10 percent cut for proctoring.
Spoo, would this be a massive headache for you?
LOL. Sure, go for it. But lets not play for cash, could complicate things. Ill donate a prize to the winner though. Someone else has to manage the pot/guesses though - I got another 250 auctions to crack out, and trick or treating tomorrow.
