Kmart clearance deals can be exceptional even WITHOUT the use of points: found a 70745 Ninjago Anacondrai Crusher on the top shelf, didn't ring up on store scanner nor price-check at the register. Friendly lady took me to someone with a special inventory scanner, who said it was $2. Then, when I paid it turned out to be marked Clearance (which is 50% off right now) so got it for $1 before SYW shenanigans. Found more old sets, applied $5 off $35 coupon, which made my pre-points total $0.82.
To top it all off, the register printed out a $5 on $5 Freecash coupon and a $5 off $25 toys coupon. Not too shabby.
