Why is SICP so damn expensive?

I can't find it for an affordable price anywhere. Is this book made of gold or something? I hate reading on my PC. Sorry /prog/, but I won't be reading it.

Kind of a beginning programmer/lurker here, why should I read the SICP?

I see it posted all over /prog/

I actually wanna know what's in it that would be beneficial to me
