When I printed my Scott coupons on coupons.com it also printed a form to mail in for coupon rewards.
Buy 2 different Scott product categories (tissue, paper towels, napkins, wipes and scrub cloths), get $2 in Scott coupons. Buy 3, get $3 in Scott coupons. Buy 4, get $4 in coupons. Coupons will be sent via email.
Fill out the form and send in with your receipts, and upc codes. Get the form and details HERE.
