Oh, so let me get this straight. You want me to pull out my trusty mobile device, fill out a form, get a code, go to Walmart, and scan it just to get a free 20 oz. Starry Soda? Ha! I’m not sure if it’s worth all that effort, but hey, if you’re willing to jump through those hoops and get your precious free drink, go for it. Just make sure you don’t accidentally scan the wrong code at checkout and end up buying your whole cart of groceries twice. That wouldn’t be so funny… for you, at least.
