Dreamspinner Press, a publisher of some of the best m/m romance, is celebrating their six year anniversary this month. They are having "TweetAways" all month. That is, they post an announcement on their twitter that they will be giving away a certain ebook for the next hour along with a link to download the book on their website. If you see the tweet and click on the link within that hour, you can get that sucker for zero smackeroos. These are good books by authors like Andrew Gray, Amy Lane, Cardeno C. and many more.
[TIP: I set up their tweets to be sent as text messages to my phone so I can be sure to see them!]
Here's their twitter account:
