Lucky Charms aren't very good for you already, but if you really want to kick it up a notch, they're giving away boxes of JUST the marshmallows again.

They originally gave away 10 boxes back in 2015, then gave away 10,000 boxes in 2017. Now they're doing 15,000. You have to buy normal Lucky Charms, look for a code in the box, and enter it online to see if you won.

If you DO win a box, you might not want to open it, because it might be worth something. We found one on eBay with a starting bid of $600. And if you really want that many marshmallows, you can just buy a generic bag on Amazon for 10 bucks.
