If you text VALPAK to 727272, you'll get a free Redbox rental code for a free movie or video game. The code should work online, in the app, or at the kiosk. You'll only get the first night free, so don't keep it for longer unless you want to pay for a second night.
Your free code doesn't expire until 2/28, but I wouldn't blame you for using it while the little ones are home on school holiday. Thankfully I don't have to share my free codes with anyone since I don't have children of my own. It's one of life's little treats for being forever single!
