There were SOME deals in the mixed shelves of random clearance/closeout stuff. I did walk away with a decent (not unheardof) price on a Incra miter slider for the tablesaw and a few other things ... but IMHO a lot of the stuff was just not marked low enough to actually move it. Lots of just random stuff that to the right buyer might be a gem in hiding ... but to me, mainly unneeded stuff still marked too high for a "what the heck" buy.
With that said ... Klingspor in general has improved what they carry from where it was about 2 years ago, or so, and you can get pretty much anything you need there. But good luck finding it in stock. They keep a very low inventory and more times than not what you need will have to be ordered, or brought in from another store. So go with patience!
The best deal I probably saw was a Veritas tenon cutter for half price ($13), and some of their lower end sandpaper for $5 for 50 sheets (good for general use). They also have bundles of 5" circular sandpaper for $5 too, I believe.
And remember ... in Charlotte they close early on Saturday and are closed on Sundays now.
