# After I'm finished reading, I can sell my Kindle book back to a used Kindle bookstore?
Actually, it occurs to me that this might be a consumer-friendly use that DRM could facilitate. If you've purchased a plain text file or an "unprotected" pdf or whatnot, the store has every reason not to buy it back because there's no incentive for the customer to delete the copy he purchased. Some probably would, but too many wouldn't.
There would be no physical copy to return, so that the store could resell it. But if they can "deactivate" your copy, why not offer the option to sell it back? Maybe they could offer the choice at the time of purchase:
( ) Click here to purchase a DRM-free copy. You will not be able to sell it back to us.
( ) Click here to purchase a DRM-encrusted copy. You will, if you want, be able to "sell it back" to us later for half of your original purchase price.
Or something. I don't know; the idea came to me just now and I haven't thought it through very far. Maybe there's some reason why it wouldn't work at all.
