One of my favorite sites, Hollar, has a bunch of great Disney Planes: Fire & Rescue Movie Digital Download on sale for only $2 today if your kiddos love this movie!
When you make your purchase, you will be mailed a unique code and download instructions. I have done it myself and it worked great! They actually have a bunch of other Disney Movies for $2 available, so check around and see if they have anything you like here. You have to spend $10 to get these prices, but that means you can get 2 movies for $5 each :)
You get Free Shipping on your first order or when you spend $25 or more!
