The deal is even BETTER because it overlaps with a few other catalina deals: (This information came from Common Sense with Money)
*Get $5 RR when you buy three Wyeth products (ends 12/31)
*Get $5 RR when you buy $10 in Wyeth products (ends 1/31)
*Get $10 RR when you spend $20 (ends 1/31)
The Robitussin/Dimetapp is on sale for $4/each this week (I believe the regular price is $5.99). Print five of the $2 off coupons (the links are posted here). Then, if you can get your hands on five bottles, you will spend $10 out of pocket after coupons, but you will get $20 in RR (if you buy them before 12/31). After 12/31, you will get $15 in RR.
Since the $15 overlap will continue through January, if your store is out of Robitussin/Dimetapp, ask for rainchecks for the $4 price!
It’s a great time to stock up on cough syrup! 🙂
