The phrase "rip (someone) off" means to charge too much money for something:

They charge two hundred dollars an hour? They're ripping you off!

Call something "a ripoff" when it's way too expensive.

Eighty dollars for a meal? What a ripoff!

If it's even more expensive, call it "a complete ripoff".

You can call a store, a restaurant, or a single product "a ripoff".
