Query: What a Bargain!

Whilst this is a beautiful book in all dimensions I am astonished by the price here. It is imitation leather which I purchased for some $30 from a first-hand bookseller. Even by going to a second-hand book seller, one could have this book ordered in in mint condition for no more than $150. I am simply astonished.
