Kobo tells you when books have DRM and when they don't (at the bottom of the store page for each book). I'd recommend supporting them over Amazon any day. Besides that, a lot of publishers who sell their own books do so without DRM by default. As does almost every book bundle hosted by Humble Bundle.
