I recently found this app on Facebook that some sites use for giveaways. Basically you need to share the item you want in your wall and then just keep your fingers crossed. Best thing is that if a friend of yours who clicked on your link wins, you win too! Give it a shot:Log In Hopefully I'll get an item someday!
Good find! I've entered a load so I really hope my friends click on one. My timeline's looking pretty full! Anyone who doesn't at least enter to win the gift card's is mad!
