Plain and simple, if the moderators wanted more forum visitors to see this extremely limited time deal instead of just adhering to auction thread classification semantics, they SHOULD have left it in the deals forum. Luckily, the "moved" link stays for a while, so most that were there should have seen it in time.
IMO, the auction section is for every random 1 of a kind auction deal that might be hot, not for large scale sales from a retailer like buy.com.
