A lot of you have been disappointed because ebay has been removing the sc2 key auctions. Here's a way to sort of get around that. Lots of people package the sc2 key along with the wow mount, and some even package the card (containing both keys unscratched) with the rest of the blizzcon bag.
So bid on one of those auctions, and then resell the wow mount on ebay. The mounts alone are going on average for around 200-300 bucks!!! I started my auction to resell mine for $0.99 and it's already up to $152 with 3 days still left. Since I paid about 250 for the package of unscratched card + blizzcon goodie bag contents, if the resell price goes above 200 bucks I will have paid only 50 bucks for a sc2 beta key and the blizzcon goodie bag contents (which are awesome, btw... lol the diablo 3 "sinamints" are amazing).
I saw on some other threads some people saying they were willing to pay a lot of money for one of these keys, so 50 bucks shouldn't be too bad, especially considering you get the blizzcon goodie bag contents along with it if you bid on one of those auctions.
I'm sharing this with you guys because I believe everyone on team liquid should be in the sc2 beta All those kids that just play wow are wasting their cards, while plenty of hardcore starcraft players are left empty-handed.
Good luck bidding! I hope all of you get in the beta
Edit: ONE OF MY AUCTIONS FOR A MOUNT JUST SOLD FOR BUY IT NOW FOR 300 BUCKS LOLLLLLL THATS A PROFIT!!!!
