Amazon's delivery fees for Kindle books putting a hurt on publishers of graphic novels, comics

PW: "However, while there is a nascent market for comics on e-book readers like the Kindle and B&N’s color device, the Nook, Amazon’s recently introduced digital 'delivery fee,' charging publishers 15 cents per megabyte to transfer a book’s file to the Kindle, has forced some comics publishers to rethink using the Kindle platform. While novels are text-based and unlikely to run up a delivery charge much over $0.02, graphic novels have a much higher bandwidth, and could be forced into a lower payment/royalty rate and higher list price because of their file size, directly because of these Amazon fees. In addition, Amazon also has a recommended file size which affects graphic novel pricing."
