WARNING: Redeeming this freebie will auto-play a video loud enough to wake the dead and scare the ever loving crap out of people named Goob.
Click the brown “REDEEM OFFER” button on this page in order to get a free NITRO Pepsi at Walmart. Once you click the button, a stupid 10-second video will play, then you can “scratch” away the screen and enter your email address. They'll then display a Walmart gift card worth $1.88, which you can add to your Google Pay app or Apple Wallet app on your phone.
The button is coded to only appear on mobile devices, however you can still easily get this on a desktop computer. Just resize the browser window and make it smaller. Once you get it small enough, the button should appear. In case you don't understand, I made a little video showing what you need to do.
