I got the following info via PM from trackers55. Unfortunately I don't have the 15% coupon. However, I received 10% amount of Sears points coupon via email, so check your Sears emails. I was hoping that I can applied both coupons...
It should be in your shop your way rewards acct on sears.com go to the top and click on coupon deals then you should see a coupon for 15 percent off and click on it to apply it
