Amazon has Corel AfterShot Pro digital downloads available for $25 (boxed copies are $64). I first saw AfterShot Pro last year at CES 2012. It’s raw photo editor and an alternative to Lightroom; however, it does some things different and some stuff that Lightroom can’t. That said, I haven’t heard much news about AfterShot Pro since then and I’m not sure about the current state of development.
You can get the download deals for Windows or Mac here on Amazon.
