Answer:
The Correct answer for: Bookbinder Books partnered with Amazon to offer a unique _________. If you purchase 1 of 12 paperback books published by Bookbinder, you can choose 1 of 12 Kindle versions for $3 (a much lower price than a regular Kindle version). Is: Bundling
Step-by-step explanation:
To understand this question we have to analyze the context and it's meaning so here we go: First of all we have the case telling us about a special offer provided by bookbinder and Amazon. The offer consists of a package of books that is open to free setup by the customer. However, it has a few requisites. It has to be a 3 book package and their respective price is 3 USD each. The only thing that the buyer decides is the title. So we are talking about a bundle because a bundle is a package o hardware that is set to be together on a special occasion. But that regularly is sold apart.
