If your kids have been itching to see Wonder Park [1] and you have an Amazon account, you may be in luck! The movie ticket website Atom is currently running a deal [2] that lets parents snag a kid's ticket for free. All you have to do is go to Atom's page [3] — or download the app on your phone — and create an account using your Amazon credentials. From there, simply buy two or more tickets to have the discount automatically added to your order. And, yes, you can buy either two adult tickets or tickets for one adult and one child to qualify for the deal. And FYI: the offer is only valid for purchases made between March 11 through March 24, while supplies last. The movie hits theaters on Friday, March 15. Don't forget the popcorn!
