[Buying]  Cheap Stadiums?

Chrismas is approaching band the only stadium my brother and I have is a tiny, taped up, yellow one with walls all around. Does anyone know any good, cheap stadiums we can buy online?
Probably the blue Hasbro one
I have a Hasbro Bolt Blast Stadium, Burning Firestrike stadium, Mobile Beystadium, and Blazing Dojo Beystadium. Would you be interested?
Cheap and stadiums do not work together.
