Goodreads reviews

I've read through most of the posts and haven't seen this mentioned, but I have seen a lot people mention that they like physical books better than ebooks. Goodreads has been a great source of free books for me. Not ebooks, but the actual physical copies. I don't know exactly how they work, but I have entered a bunch of giveaways. I don't win them all, but I've received a whole bunch of awesome books to review. And they've all been the actual first edition, not a galley copy. I don't think you're strictly required to review anything you win, but it's obviously what they are looking for. Most of the authors ship the books directly along with a nice note.

ETA - I know it's "free stuff" but since they do it specifically to get reviews without saying it's required, I thought it's most appropriate here. I'll delete if it doesn't belong here.
