I drove 30 miles to my nearest Kmart because I needed Christmas outfits for my kids. Got up to the register and the cashier asked me if I'd like to sign up for email alerts. I pulled out my "coupon" and said, I already am! She was really nice and started ringing my stuff up while looking for a manager to figure out how to "run" the coupon. The cashier next to her said, there is nothing you need to put in, everything that would qualify is already ringing up the discounted price, that is just like an advertisement. My cashier was like, but it says "coupon". Upon reading the fine print at the bottom, it said it wasn't valid on sale merchandise, but only on regular price or clearance. Well, since I'm always after a great deal, everything in my cart was sale merchandise, so I couldn't really say if it "worked" or not. I wasn't that upset, because I did get some good deals, but an extra 20% off would have helped! Kind of pointless for them to send out such a useless email! lol
