What is the English idiom about "expensive" that expresses the idea that "It is so expensive that you feel like you got ripped-off"? [closed]

exorbitant is also used for extremely unreasonable prices.

An example of using it, quoting the Oxford dictionary:

some hotels charge exorbitant rates for phone calls


Pay through the nose is another common expression:

  • Pay an excessive amount for something, as in: We paid through the nose for that vacation.

    • The origin of this term has been lost. Possibly it alludes to the Danish nose tax, imposed in Ireland in the 9th century, whereby delinquent taxpayers were punished by having their noses slit. [Second half of 1600s]
