Good points, thanks. I didn't look because I'm not interested in DRM'd files - never "bought" one yet. Arguably, it may be deceiving the customer to have the buttons say "Buy" instead of "License".

You may return a particular Online Book for a full refund within 30 days of your purchase date, provided that you have not accessed more than 20% of its digitized pages. Interesting. P.S.
