&gt; Trying to &quot;get my money worth&quot; shouldn&#x27;t impact your decision<p>Why not?<p>By purchasing the e-book version a customer is surrendering potential future revenue ( resale of physical book or trade-in against another  ), but is not being offered much or any compensation for this loss.<p>If the Kindle edition is £66.50 and the hardback is £70.00 [0]  I&#x27;ll laugh at the publisher&#x27;s e-avarice and buy the physical copy; I&#x27;ll likely make about £45 back when I resell it.
