Not buying eBooks from suppliers that infest them with DRM doesn't mean not buying eBooks. I love my Kobo reader with all my heart and it has massively increased my consumption of fiction. Just don't support and buy eBooks from suppliers that use DRM.
There are quite a few more, but I don't want to link them because I haven't personally used them. I'm also hoping DRM-Free eBook bundles catch on (https://www.humblebundle.com/).
If there are books that I "desperately" want to read and can't find them in DRM-Free form, I visit the local library. If the library doesn't have it, I will buy a print version. As long as it isn't a technical reference manual I will use frequently, I then donate it to the library when I'm done with it.
For all fans of fantasy and science fiction, the dragonmount.com is also a DRM free webshop for ebooks. (I have no affiliation with said site, btw. Just a happy customer).
While http://dragonmount.com is a Wheel of Time community they sell the entire range of DRM free TOR science fiction novels (among others). Definitely a good place to shop.
I just tried entering a bogus US address, and got as far as the page where you can choose a payment method (which includes PayPal, so presumably you don't need a US credit card). If you get access to the books as a download, I suppose that you actually would be able to buy a book in this manner... Has anyone tried doing this?
Baen Books is my favorite for science fiction. (www.baenebooks.com) O'Reilly Media for technical books. (http://shop.oreilly.com/category/ebooks.do) Calibre eBook store. (http://drmfree.calibre-ebook.com/) Project Gutenberg for the classics. (http://www.gutenberg.org/)
