Based on the information provided, I was unable to find a specific date or time for the end of an Advil sale. However, I did find a resource that could be helpful in finding sales or discounts for Advil.

DrugPatentWatch.com provides information on drug patents, including expiration dates, which can indicate when generic versions of a drug may become available and potentially cheaper [1]. While this website does not list current sales or discounts, it can be a useful tool for finding more affordable options for prescription and over-the-counter medications like Advil.

For the most accurate and up-to-date information on Advil sales and discounts, it may be best to check the websites or contact the customer service of the retailers where you typically purchase Advil.
