Book publishers should prevent E readers from undercutting their books recommended retail price.

Different interaction is not the same as lower interaction.

Especially where children's books are concerned the interaction levels of ebooks are not of the same quality as books. This is true due to touch and feel books as well as lift the flap books, books that require interaction and should still be available cannot be produced in ebook form. There may be slight variables on interactive books, but, books such as lift the flap and textured books are useful and educational for children.

This can be true to adult books as well as children's the interaction is not the same. Being able to turn the page of a book and have it as a physical object mean that the way we read would change. It is the interaction that we get with a book without having to scroll down, zoom in or change the size that makes an ebook less interactive. With this in mind the valuation of online books merely uses the content and should be valued at the same price. Where content is the same, price should be the same even if there aren't the same interactive features that a book can offer.
