Should be outlawed. Unfair to the weak. I'm done with lathes & equipment for a long stretch...did take advantage of 15% off Jet stuff years ago. However this season I kept getting 20% off emails from an Audio Company (Audioengine). I have one of their systems from several years ago. I could not stand having 20% off shoved in my face repeatedly without taking action. I folded..bought 2 new systems. One for the bedroom with a bluetooth sub and a small desktop set for the computer. I hate myself.
