Tracked by Evreward since 2010, Build-A-Bear Workshop offers coupons, cash back rebates and rewards, with savings as high as $40 off. Build-A-Bear Workshop discount coupons are rare, only available once or twice a year, but are often more valuable than similar merchants. Even when Build-A-Bear Workshop doesn't have a coupon, you can always get up to 10% cash back, and other great rewards, with every purchase.
