There is an Apple support "contact us" link at the bottom right of every page of these forums
The low Resolution warning has been reported as MIA - so you may be exactly correct there
As to quality - very few omplaints here - in fact there probably are as many praises as complaints w=hich is very unusual for a problem solving forum - so I suspect that something went wrong with yours - how did the preview look before you submitted?
Before ordering your book preview it using this method - http://support.apple.com/kb/HT1040 - and save the resulting PDF for reference - the delivered book will match it.
I've visited the contact us page -- so many options I'm not remotely clear on where to ask about returning a book and frankly, assume I'm going to hear that image quality and the font issue are on me.
I've loved my books in the past -- calendars, cards, I've done it all. So this is truly an anomaly. It's the dull color quality that is really sad.
Any clues on which of the many support options to pick on that page? Thanks for the preview link for next time.
