an arm and a leg

Hi,

I'd like to know whether the idiom "an arm and a leg" is still used nowadays (to me it sounds chiefly British and like something straight from the 18th century). I've always used "cost a fortune" with the same meaning. :-D

My own Example: This English textbook cost me an arm and a leg! I swear to god, it'd better be the greatest English grammar book ever existed on the planet or I'm done with this publisher.

Thank you in advance.

With kind regards,

It is pretty common in my homeland, Canada. I don't think of it as British.

Thank you. Am I right to assume that if it's common in Canada, it's also understandable in the US?

Definitely.

Yes.
