Not sure if it's been mentioned, but there's a 20 points back on $40 promotion/coupon at Kmart. Could be a good deal with the new Star Wars sets. Additionally, the new sets aren't marked as Hot Buy, so you can stack additional dollar off coupons.
I was able to get 2 Carbon-Freezing Sets, 75137, for about 45 with 20 in points back (had a 5 off 35 toys coupon I was also able to use).
If you want to apply the coupons manually, just copy the code:
