I stopped by a little watch shop in the local mall this morning called "Precision Time." (Similar to a Sunglass Hut) and they had ALL their Casio's on 20% off clearance. Everything from G-Shock's and Baby G's to Pathfinders
They are nationwide (CONUS only, sry Europe and Asia ) and here's a link to their site to see if you have one near http://www.precisiontimeco.com/locations.php .
I don't know if it's a nationwide sale or just local to OKC,OK,USA but if you're in the market, happy hunting!
