If you’re going to bundle a code for a free e-book copy with a print book (and charge a little extra for the deal, as with these DVDs), you’d darned well better honor that code for as long as you’re publishing that edition of the book.
[…] e-books aren’t milk. There’s no earthly reason they should have a sell-by date.
While this Teleread article mainly talks about DVDs, the ending has implications for bundling an ebook with a physical book. Specifically, this is the idea that the publisher would offer a book/ebook bundle at a higher price with a limited time offer on the ebook end of the deal. Beyond the idea that there would be a time limit on a redeemable code for the ebook, I can only imagine that there would be an issue with people attempting to re-download the book for whatever reason and being denied the opportunity to do so. While I do like the promise of such a bundle as someone who owns an ereader, there are some outstanding logistical questions that remain to be seen.
