Comixology is pretty much the one and only digital comics retailer. Virtually every book that hits the store shelves is sold day-and-date on Comixology. Everything releases at cover price initially, but the price of non-Marvel books drops after one month, and the price of Marvel books drops whenever Marvel feels like it.
The only major publisher who doesn't sell through Comixology is Dark Horse. They have their own separate store
(here). Like Comixology, they release pretty much everything at cover price, but drop the prices after one month.
Marvel has another program called "
Marvel Digital Comics Unlimited", but it's very different. For a flat monthly or annual fee, you get full access to a huge library of digital back issues, including a lot of complete runs. It's an older service, but Marvel still maintains it, and they add to the library every day. It's a
great way to dive into Marvel's enormous back catalog on the cheap, as long as you don't mind reading comics in a web browser.
