META: Online comic book stores

Due to some recent unpleasantness at Heavy Ink, folks without local comic book shops are looking around for a good, reliable comic book vendor retailer online. For instance, I am in the middle of nowhere and at least 2-3 hours away from the nearest shop, so I need to get my fix through the mail. The Marvel Digital Comics are nice, but they're only Marvel and they're only digital.

Do any of you have recommendations on a good online store to manage subscriptions to a variety of titles?
