Tracked by Evreward since 2006, KitchenAid offers coupons, cash back rebates and rewards, with savings as high as 44% off. KitchenAid discount coupons are infrequent, only available a couple times per year, but are often more valuable than similar merchants. Even when KitchenAid doesn't have a coupon, you can always get up to 15% cash back, and other great rewards, with every purchase.
