Here's some giveaways I've seen around just today:
Serena at Savvy Verse and Wit is celebrating her blogiversary with three different things to giveway, all them very cool. All you have to do is go comment!
Natasha at Maw Books is celebrating Stephenie Meyer by giving away a bunch (like ALL) of her books and other Twilight type goodies. Amazing contest, you have to go check it out.
Susan at West of Mars has a fun book to give away, just because she likes the book and wants to!
