You just need to figure out who to trade with. That promotion brought in a lot of noobs (myself included), and either because they don't trust the site, or they are looking to make killer profits, some of them price their items really high, and or don't accept trades.

The site is pretty cool, but again you need to find the good traders. I can recommend Tiddley Winks, Moviebuff, Sammy, and Switch_This! off top of my head.
And as far as sending out, I tend to only accept request from people who have a trade history, or have items up for trade, and have fair priced items. so if you have Gears of War for 80SB I won't accept your request. I don't want people getting my stuff on the cheap, and then relisting it with a much higher price. That's what is hurting that site now.
Anyway I hope this helps anyone who joined the site, but hasn't been able to take advantage of it yet.
