This is what I was kind of doing for books in Barnes and Noble: check the contents, read a few pages, then buy the e-book or physical book online. With this app it would make it super convenient to compare prices and order instantly after doing such a thing. I would imagine this will extend to clothing and other things, i.e. people will try the clothes and look at stuff in physical stores then order online if there is no rush to have the item. Who would have thought the online world would be such a force to reckon with?
