Query: No access to online materials from kindle version

This is not a negative review of content. I purchased kindle version in order to get quick access to all of the online worksheets. Cover of kindle version says it includes online access and price was only $2 less for kindle, so no reason based on price to limit online access to only print book purchasers, yet password to online materials was not in kindle version. I can't print from kindle, so what good is a workbook for kids that they can't use? Spent 20+ minutes on phone with the publisher, but they kept sending me around and around with no solution. Finally just returned it. Very frustrating.
