to break the bank (to be too expensive)

Eg 1:

A: I like your new car!

B: Thanks. I bought it second-hand so it didn’t break the bank.

Eg 2:

A: We haven’t been out for ages. Let’s try that new restaurant in town tonight.

B: Oh I don’t know, we don’t have much money.

A: One night out isn’t going to break the bank! Come on, we never go out!

Have you bought anything that “broke the bank” recently? What did you buy?
