Did you check your receipt to be sure? I was just there this morning and bought a ton of stuff. I gave the cashier my 30% off coupon which she scanned, and on the screen I could see it took 30% off my total. I then gave her my Kohl's cash which I assumed would be deducted from my new total. Now I am looking at my receipt and used a calculator to double-check and NO, the Kohl's cash was deducted FIRST, meaning my 30% off got taken on the reduced total. In my case it came to a $21 difference. So I paid $21 more because of the way their computer processed the transaction.
