They've been this price for at least a month.
I bought a set, and only after read the reviews. They aren't bad enough to return, but they aren't good enough to recommend.
The finish is much nicer than the orange-handle Harbor Freight pair I compared them with, but they aren't as good of a tool. The tongue is sloppy in the groove, getting worse with larger opening grooves. When they are in the largest size groove they jam and are very close to coming out of the groove. Breaking the peen on the adjustment screw and tightening won't fix this problem. Machining might fix it, but then you lose the nice finish.
