I'm not getting the $4.99 upgrade option after registering my old physical copy of Information Architecture.
Is this no longer offered?

Our website doesn't offer the ebook upgrade discount for a book when there is a new edition of that book available. That's why it offers the upgrade to the next edition instead. We do still offer the $4.99 ebook upgrade for that edition, but you need to call our customer service folks for that. Since it took so long to answer this, I went ahead and just gave you that ebook for the first edition. It looks like it is only available in ePub format, though.
