All Romance eBooks is having their free book a day now, though it's not from the beginning of December to the 24th like it was. It started on December 13th and runs through the 24th. JMS Books is offering a free book a day. They'd been doing so since November 25th, but I heard about it on the AE "Gay Books -- What We're Reading" forum a couple of weeks after that. I've picked up a couple of the stories. I also got books that were on sale there, as they're having some good sales as well.
Later: I read "Sock It To Me, Santa!" by Madison Parker. I'd seen that recommended on the AE forum.
