I'll bid low on items just so it's tracked for me. That way if I feel like it later on I can either bid again or shake my head at how high the price got to (this applies to a lot of things on eBay).
$2400 for an XBox 360? What are some people on crack? They couldn't wait 14 days for them to be at all the retail chains for $450? A buddy of mine bought two at FutureShop for $450 each (Canadian) and sold them on eBay 3 days later for $600 each... then he went back to WalMart and bought another one for his kids (so basically he got an xBox 360 for $150 for Christmas).
