Here's what happens.
If I get into the "premium catalog" on Smashwords and my book doesn't have a set price they will give it a predetermined price of $4.95. So I have set the price for Filter at $2.99. For now you can use this coupon code TZ68P here http://www.smashwords.com/books/view/20957 and download Filter to your nook, iPhone, iPad, Blackberry, Android, PC, Mac, or Kindle for FREEE. Or just go to Amazon and pay $2.99!
