That’s a rip-off!

Storyline: Jack bought a used computer for 400 dollars without realizing that he had been ripped off.

James: How much did you pay for it?
Jack: 400 dollars.
James: 400 dollars for a piece of junk like that? That’s a rip-off!
Jack: What do you mean by that?
James: Don’t you understand? Now you can get a brand new computer for less than 300 dollars. Then why do you have to buy a used one at that price point?
Jack: Oh. I guess I really got ripped off.

Notes

To get ripped off is to get cheated or exploited.
