This new "pre-order" functionality on half.com is neat. You list an item and its like "Hey, do you want to sell it for $x.xx right now? Someone has a preorder in for that price".
Went out with the lady and bought two copies of Fantastic Four extended from BB for $6, took out the movie tickets, saw the movie, came back and sold it on half.com for $8(lowest used price was already 8.99 or something)
