Cost an arm and a leg!

(Informal) Be extremely expensive. Cost a lot of money.

Mary’s dress is pure silk. It must have cost an arm and a leg.

It cost an arm and leg, so I didn’t buy it.

Notice how interesting is the way idioms work in English and give this fluency to the situation. Similarly, we in Brazil have a lot of idioms and for the one here, we also use part of the body to describe something as expensive: “custar os olhos da cara”!

A piece of cake

Fig. Something easy to do.

No problem. When you know what you’re doing, it´s a piece of cake.

Cultural note: in most of the idioms using the word cake it is used as a metaphor for something pleasant or desirable.
