Quite a few. Found some good trades recently. Also bought a number of the new Phantom Manor pins. I've managed to trade for a few Ezra pins too. Though I find I might begin to run out of space on some of the pages in my pin bag.
My collection isn't that big yet; but hey its getting there. ^_^;
O_O You don't have to do that! I've been getting a lot of zaps recently for some reason and I'm getting quite embarassed about it as I don't have many traders so don't really have anything to zap with in return etc. ^_^; (I'm hoping to go on a pin spending spree if I get to DLRP this year... then I'll have lots of traders!) Are you sure you don't want anything in return if you do win it?
