A novel printed in paperback that sells for more than the same book in an electronic format

The example contains two different products, one is novel in paper form, and other in electronic form of the novel. Price discrimination occurs when we charge different prices for the same product from different customers. They are completely two different forms of the product which means the product is not identical in term of its form.
