Amazon offers Prime members the Funko Pop! Rides Hogwarts Express Engine with Harry Potter Action Figure, model no. 5972, for $19.02 with free shipping. (Non-members can spend $49 or more to qualify for free shipping; otherwise, shipping costs $6.47.) That's the lowest total price we could find by $5. It won't really take you (or your figure) to wizard school, but you can connect it with the Ron and Hermione pieces to form a pretty sweet train.
