Tracked by Evreward since 2010, Renew Life offers coupons, cash back rebates and rewards, with savings as high as 50% off. Renew Life discount coupons are seasonal, appearing every three to four months, and are often more valuable than similar merchants. Even when Renew Life doesn't have a coupon, you can always get up to 15% cash back, and other great rewards, with every purchase.
