Not to derail this for anyone that's interested in buying digitally but I've been able to read a ton of graphic novels over the last few years online due to having a library card. I use the app Hoopla, which my library card gives me access to. Saved me a ton of money and I've had access graphic novels from DC, Marvel, and plenty of other publishers. Saga was probably my favorite one I've read over the past couple of years.
