Ecotrin Coupons

My husband asked me for some aspirin earlier today and when I opened the 45 count Ecotrin box, the inside of the box had a $2 OFF coupon for a 60+ count box! You can also register

here to print a coupon. I don't know the value of the coupon since I don't need to buy any right now, if you know the value, please let us know!
