Well in the story Jasmine was the second born and already had a lover that her father would allow her to marry when she ends up being Queen, because he isn't royalty and instead she would be forced to marry Jafar. So she made a deal for a potion to turn him into something she couldn't marry without killing him. But her lover is going to drink it instead. I don't want to give it all away though that is how Jasmine will get her tiger, she wouldn't actually offer a price, she would have given him anything he wanted. Does that help with the price at all?
