Kindle - Free with web purchases - Download now (opens in new tab).iBooks - Free with in-app purchases - Download now (opens in new tab).Right now, to get as many comics as you want, you have to use both of them, even if it does split your collection and is otherwise less-than-ideal. Why include both iBooks and Kindle, why not pick a best or just pick one and stick with it? Sadly, both sometimes have books the other one lacks or have them in geographies the other doesn't or have it at a lower price. With Amazon, you can buy via (opens in new tab) and download to the Kindle app. With iBooks, you can buy directly within the app.

If you don't want to buy or read each comic as it comes out or navigate through tons of back catalog to find specific stories, buying them as books is the simplest, most coherent way of doing it. IBooks and Kindle are general purpose readers, but both Apple's iBookstore and Amazon's Kindle Store have an excellent selection of what used to be called trade paperbacks - collections of individual issues that form a cohesive story arc.
