Burger King is offering free Big Whopper burgers to those who have Burger King in their Zoom background. To claim, just use it, take a screenshot and upload it to your social media, making sure to tag them so they see it. Zoom is currently free too, so this can be done for absolutely nothing.
Once Burger Kings reopens after lockdown, you'll be able to claim your free Big Whopper! Offer ends 17th April 2020.
