Everyone has experienced that moment during the holidays when opening a gift, only to quickly wish it was something else entirely. For the holiday season, Burger King restaurants are offering a Whopper sandwich in exchange for an unwanted gift. Who says miracles don’t exist?

All guests need to do is head down to the Burger King restaurant located at 910 Arthur Godfrey Road, Miami Beach, between 10:30 a.m. and 5 p.m. during Boxing Day on December 26 to swap their unwanted present for a flame-grilled Whopper sandwich. The exchange will be taking place across the globe in select London and Brazil restaurants as well.

If you are unable to make it to the restaurant on December 26, don’t worry. The first 100 lucky fans to post a picture on Twitter or Instagram with their questionable gifts using the hashtag #WhopperExchange will get a surprise from the Burger King brand’s social media accounts.

“At Burger King restaurants, we are always looking for ways to surprise our fans, no matter if they were good or naughty,” says Fernando Machado, SVP Global Brand Management, for the Burger King brand. “The Burger King Exchange will offer our guests the chance to get a flame-grilled gift in exchange for an unwanted one. Because this holiday season, we want everyone to receive something they will love.”

Burger King restaurants will donate all gifts to charity, because someone’s unwanted gift can be someone else’s treasure.

In the U.S., exchanges will be limited to a certain number of gifts accepted at the 910 Arthur Godfrey Road, Miami Beach, location. Acceptability of item to be determined by Burger King Restaurant personnel in their sole discretion. Restrictions apply.
