A top Evreward merchant since 2005, Kohl's offers coupons, cash back rebates and rewards, with savings as high as 90% off. Kohl's discount coupons are plentiful, usually available every month, but can be less valuable than similar merchants. Even when Kohl's doesn't have a coupon, you can always get up to 16% cash back, and other great rewards, with every purchase.
