Amazon also offers the Kindle digital e-book version for $11.87. The cost to Amazon to produce a new "copy" for the next consumer is virtually nothing: ;ust the sending of some data to the customer's device.

Amazon has to charge a price that is comparable to the prices for physical copies of the book since, if it charged even slightly below those prices, virtually all customers would switch to the digital version and Amazon would be unable to supply the extraordinarily high demand for the e-book. O b. People who would consider purchasing the Kindle version likely consider a digital version of the book to be a close substitute (maybe even preferable) to a physical copy of the book, so even though the cost is low, the publisher can still charge a price that reflects the demand of these customers for physical copies, and these customers don't ccgtmpiain.
