I posted it on the Twitter feed which shows up on this page but I may as well put it here too: as part of their Summer Reading promotion on Smashwords...
I've put all three Pont-au-Change books on sale!
You can get them for 50% off with the code SSW50 at checkout, now through July 31. They were cheap to begin with but now they're SUPER cheap! So if you've been putting off getting them, or you've been telling people about the books and they've been waffling, now is the time.
Link to the sale here!
