"and you will receive a full refund of the original purchase price."
Seems fair enough to me.
Seems fair enough to me.
Can I use the money to buy the same book? Is my time lost searching for this replacement worth nothing? If I added annotations, do they end up in the new book? If you answer any of these questions with 'no', its not fair enough.
You could have originally bought it on sell and that sell is no longer available.
You could have added value to the ebook by way of adding annotations.
The ebook could have had better display than its competitors, if it and all other equal quality displays vanished, they are now very rare. Someone would be willing to pay more than your original purchase price if they could now get that display experience.
