Last week we wrote about Robitussin on sale at Walgreens. Since we posted that deal, a couple of new Ibotta offers have emerged! This month, bottles of Robitussin are on sale for $4.99. Stack a Snap offer with the new Ibotta offer and use a $1.00 manufacturer coupon. Stack the manufacturer coupon with a Walgreens coupon from the Pediatric Care Book or the Cold and Flu Book. In my store, both of these Walgreens booklets were located on the medicine aisle. Stack the savings from all four sources for a final price of $0.99!
