I am selling 1 or 2 Blizzcon tickets (badge only) here for bitcoins (or paypal, but prefer bitcoin). I've been doing this a couple years already on ebay, and have very good feedback from customers. Price is $175 USD. You can pay me $75 first in bitcoin as a deposit, and pay me the rest when we meet to give you the badge.
I have some feedback on #bitcoin-otc and happy to pm you my ebay username over PM. Please post here if you're interested.
edit: Part of the reason I wanna sell here is because there is just not much you can buy with bitcoin right now, which is a problem with this economy. I am offering a highly sought-after commodity here rather than posting to ebay.
