Around $50 USD in Amazon, like today. I just thought it was too much for the quantity of pages. But really, few programming books are as good as K&R. I still think the editorial is particularly greedy when it comes to this book. Still I don't recommend any C book, other than K&R.
If you want to buy a cheap printed version search on abebooks.com. They usually have international editions at competitive prices. I used to buy all my college textbooks from there.

Agreed.
I asked about the price because it is, or at least used to be, a lot less expensive than that, in India, from the time when I first bought a copy (when first learning C, near the start of my career), to at least some years ago, when I bought several copies of it to give to the students of a C course I was conducting for a company. In that whole period it was just a few hundred rupees (INR) in price, which is just a few USD (under $10 or so, even with the change in exchange rate over the years). I do know that publishers have variable pricing for different countries, of course.
