According to the sources provided, there are a few ways to potentially save money on Advil, but there is no specific information about the amount of discount available.

One option is to check for generic versions of ibuprofen, which is the active ingredient in Advil. According to Drug Patent Watch [1], the patent for Advil expired in 2003, which means that other companies can now produce and sell generic versions of ibuprofen. Generic medications are often less expensive than brand-name versions, so this could be a way to save money on the same active ingredient.

Another option is to look for coupons or discounts offered by Advil itself. The Advil website [2] currently offers a $1 off coupon for any Advil product, as well as occasional special offers and promotions. It may also be worth checking with other coupon websites or apps to see if there are additional discounts available.

Finally, SingleCare [3] is a website that offers discounts on prescription medications, including Advil. However, it's important to note that Advil is available over-the-counter and does not require a prescription. SingleCare may be more useful for people who have a prescription for a higher dose of ibuprofen than is available over-the-counter.

In conclusion, while there are ways to potentially save money on Advil, there is no specific information about the amount of discount available. Checking for generic versions, looking for coupons or promotions, and using discount websites may all be helpful strategies.
