A couple area stores dropped down to 50% this week, however - one that I went to, their price scanners showed 50%, but the registers were ringing at 40%, causing a fiasco.
In addition, they would not take the Ebay Digital Sears gift cards, saying it was store policy. Mind you, they'd taken them in the past, and I didn't feel like putting up a fight, but the whole situation annoyed me.
This is perhaps one of the few stores of any chain I go to that views me with a bit of suspicion and disdain. Most stores seem appreciative when I wipe out their clearance trash no one else wants.
