It feels like this book is flying under the radar a little. The base edition is only $27.99 which seems cheap for an artbook. I hope it does well, the art was obviously one of the best things about Cuphead.
For most books in the $40 range, $27 is about the average price after the discount for new releases. The CE is at $69 currently, but I believe it was in the $50's at one point, but I got in after that. So these types of discounts are the norm on Amazon, and Barnes & Nobles used to match pricing pretty closely, but they've fell off in recent years. Which means I let my membership fall off as well.
