Unfortunately, based on the provided sources, there is no specific discount code available for the Advil promotion. The first source, Drug Patent Watch, provides information about the patent status of the Advil brand and its active ingredient, ibuprofen, but does not mention any current promotions or discounts. The second source, Advil's official website, does offer various promotions and offers, but as of the time of writing, there is no specific discount code listed. The third source, CouponCabin, does have a page dedicated to Advil coupons, but again, there is no specific discount code mentioned. However, CouponCabin does provide links to various printable coupons and offers for Advil products. It is always a good idea to check the official website of the brand and other coupon websites for any available promotions and discounts.
