After reviewing the sources provided, there is currently an Advil rebate offer available on the Advil website [2]. However, it is important to note that this offer may be subject to change or expiration, so it is recommended to check the website regularly for updates. Additionally, the Drug Price Guide [3] provides information on the pricing of Advil at various retailers, but does not mention any rebate offers. Lastly, the Drug Patent Watch [1] provides information on the patent status of Advil but does not provide any information on rebate offers.

In conclusion, while the Drug Patent Watch and Drug Price Guide do not provide information on Advil rebate offers, there is currently an offer available on the Advil website. It is important to check the website regularly for updates and to read the terms and conditions carefully before participating in any rebate offers.
