Instore Best Buy has Chuggington DVDS for $4.99 like this one Ride The Rails.
There is a $4.00 off Chuggington on DVD coupon which I believe you can use instore.
Final Price: Just $0.99.
As you can get two prints per computer you may want to borrow a computer to get more!
Note: Although I believe you can use these coupons instore, I don’t know anyone who’s tried it yet so call your store ahead of time and feel free to let us all know!
