My copy of Spidey by Stern had some serious misprint damage right in the middle of "The Kid Who Collects Spider-Man." After finishing the book I returned it to Chapters for a refund and never rebought it, as I'd initially bought it at a much better discount.
I've regretted it ever since the book went OOP.
To twist the knife, only very recently have I realized that if you just ask them they'll send you a replacement copy, a policy I couldn't find anywhere on their website.
