Kobo sells some books without DRM. But there's no way to search by it, and it's no longer mentioned on the search results page. It used to be, but they removed that for god knows what reason. Now you have to click on a book and scroll down to the bottom of the page to check the download options.
But hey, still better than Amazon and Nook.
EDIT: if anyone's a fan of fantasy, all of Brandon Sanderson's stuff is DRMless. That's the example I can remember off the top of my head.

Amazon and BN sell _some_ books without DRM as well. To encompass your Sanderson example, all of Tor ebooks[0] are DRM free regardless of distribution channel.
Oh interesting, I guess I haven't paid much attention to the ebook markets since I bought my Nook Simple Touch, I've just made a habit of checking Kobo first because they were the ones offering no-DRM at the time. Good to know!
