If you have the Red Plum Insert from this week (10/28) inside you should find a coupon for $1/1 Advil with no size restrictions.
At Walmart (and probably other stores too) they have the 4 ct Advil for $.97- meaning with the coupon it can be FREE!
If you don’t have the Red Plum or just want to grab a few extra there is also a printable coupon for SAVE $1.00 on ANY Advil®PM product .
So grab yourself some free headache medicine- the holidays are coming right?
Advil PM 4ct: $0.97
$1/1 Advil PM Product, exp. 1/31/13 (RP 10/28/12)
Or SAVE $1.00 on ANY Advil®PM product 
Total: $0.03 Overage
