Also off of the twitter feed, Flying Pen Press is having a sale:
I will be putting all Flying Pen Press fiction, including #scifi, on sale this weekend for $6 each. #poker book for $9. Will tweet codes.
I think you hop onto twitter and shoot him a DM to get the code for the sale - even if you don't have a twitter account yet, it's pretty harmless to sign up, and you don't have to use the service once you've got your cheap books. I've heard James R Strickland's Looking Glass is quite good, by the way.
