Where's a good place to win books online?

[Joss]

goodreads has tons of giveaways. I've gotten LOTS of books free (so many that I've stopped applying for giveaways to give others a chance to win, lol). I've won boxes of books (more than once) and I've mostly gotten advanced copies of books. I have so many free books still to read and I just won two more free books this week.

Publishers give them away all the time and I win most of my free books from them. authors also give away free copies of their books.

ADDING: If you have a Twitter account and use the #fridayreads hashtag on fridays then you're entered for a chance to win a book. That's how I won one of my free books, lol.
