EDIT: As of Saturday night, they've run out of samples.
No worries if you missed the earlier AllYou popcorn freebie, as Walmart has you covered with their own free Orville Redenbacher's Pop Up Bowl sample. Of course, those of us who got the first offer can sign up for this one as well. I plan on eating them both at the same time and seeing which runs out first. It will be the most delicious science experiment since the time I tried microwaving 10 bags of marshmallows at once.
