1. spend an excessive amount on something
I don't want to pay through the nose for a new phone
This idiom is used to express that you had to pay more for something than it is worth, or more than what you consider being reasonable. Usually, you would only 'pay through the nose' for something if you were desperate or left with no other choice, which further emphasizes the idea of unfairness that associated with the term. This expression can be used in both a social and professional context. Phrases with a similar meaning include 'pay over the odds,' and 'cost an arm and a leg.'
