Everyone goes to the seller at the top of the stage.
Jack: Hey, how much is that hoverbike?
Seller: Ah, $2,300, my good man.
Jack: Wha!?

Jack: I don't have that much money!
Seller: Well, thats the final price, take it or leave it.
Jack: Alright..
Seller: BUT! There is one thing I can refer you to.
Seller: There is a portal to the left of here, it takes you to some rich old castle where I've heard there is hidden treasure.

Seller: Oh well, it's probably a false rumor anyway, but you can go in it if you want, no stopping you.
