Re: Multiple "Products" per page, one product Title

The offers must refer exactly to the defined book (in the <body>). As 
such I don't think  that using itemref can be avoided.

<body itemscope itemtype="http://schema.org/Book" id="MyTerribleBook">
<h1 itemprop="name">The Catcher in the Rye</h1>
<div itemprop="offers" itemscope itemtype="http://schema.org/Offer">
<div itemprop="itemOffered" itemscope itemtype="http://schema.org/Book" 
itemref="MyTerribleBook">
<link itemprop="bookFormat" href="http://schema.org/Hardcover">Hardcover,
<span itemprop="numberOfPages">234</span> pages -
</div>
<meta itemprop="priceCurrency" content="USD" />$<span 
itemprop="price">4.99</span>
</div>
<div itemprop="offers" itemscope itemtype="http://schema.org/Offer">
<div itemprop="itemOffered" itemscope itemtype="http://schema.org/Book" 
itemref="MyTerribleBook">
<link itemprop="bookFormat" href="http://schema.org/Paperback">Softcover,
<span itemprop="numberOfPages">321</span> pages -
</div>
<meta itemprop="priceCurrency" content="USD" />$<span 
itemprop="price">2.99</span>
</div>
<div>by <span itemprop="author">J.D. Salinger</span></div>
<div itemprop="bookEdition">2nd Edition</div>
</body>

A second issue is with respect of the bookFormat: while it is defined by 
Book  and, as the name is singular,  looks for a unique value, the 
ablove example is about a Book  printed with two formats.

> Though of course, if this syntax is valid (certainly not guaranteeing that:) it would increasingly complicated to add other Book attributes specifically for the types Paperback and Hardcover (e.g. number of pages, ISBN).  Though this does allow you to have a single entry for any of the book's shared attributes (e.g. title, author).

A hotel room that has a different price to stay on Saturday than on Wednesday, but is still the same hotel room; a used car that has a different price depending on condition, but is still the same make, model and year; an MP3 player that has different availability based on color, but is still the same make and model of MP3 player; and so on.
