Just in time for Memorial Day: cheap and in some cases practically free beer.

Bud Light’s parent company, AB InBev, has launched a promotion offering up to $15 cash back to win back customers for the top-selling beer in the US.

The web address of the promotion is BudLight.com/BudLightOnUs.

US residents can send proof of purchase of a 15-pack or more of Budweiser, Bud Light, Bud Select or Bud Select 55 to this link to receive a prepaid card worth up to $15. Customers will have until May 31 to make the purchase and up to six months to use the card.

The promotion follows the ongoing backlash to Bud Light’s decision to choose transgender influencer Dylan Mulvaney as its spokesperson during March Madness. Many customers also responded negatively to comments made by Alissa Heinerscheid, who took over as Bud Light’s vice president of marketing last June, in a recent podcast. Among other things, he urged the brand to be more «inclusive.»

AB InBev did not immediately respond to a request for comment.

According to data cited by Beer Business Daily, Bud Light sales continued to fall during the week ending May 13, as negative sentiment towards the drink continued to rise.

AB InBev shares are now down 5% year-to-date and nearly 14% since the Mulvaney clip went online.
