Cheap, Cheap!

 is a random encounter in Magikarp Jump.

Dialogue
Event Trigger Text: Oh? Hold on. It looks like someone is heading this way.

Man of Mystery: Hey, you! Kid! This is your lucky day!

I've got a real prime item right here, and I'll sell it to you on the cheap - but just this one time!

This kind of chance doesn't come around every day! So you'll take it, right?
