I was curious myself, and I noticed that on Amazon.ca it's also only available at a high price from 3rd party sellers, though it's available from Chapters, a Canadian online bookstore, at its regular price. My own copy does have some printing issues on one page, and they are a key lines, though I have seen other copies that didn't have these printing issues.
