A couple years ago I think it was Amazon that had the 4 Bessey K clamp set for 100 bucks with free shipping, two 24s and two 40s. Well, Woodcraft has their version of the Besseys for the same deal this weekend. I have some of the Woodcraft version and they are essentially the same as the original Besseys, though the handles are not as nice. The $99.99 price is good till June 26th (with a while supplies last caveat) but free shipping ends Monday.
