Buying an ebook with a physical book

Let's just be honest: We'll miss the bookstores. We'll miss then, but they're going away. One by one, they're selling their last book, customers at home, buying books on their electronic devices.

But nothing beats casually walking around among hundreds of books, randomly flipping through pages.

Then, the awkward moment where you find a book you want. It's not against the law, but you know the risk is there: being called out as a showroomer, searching for the book on Amazon, right in the store.

What if you could just point your phone at the book and save that book for later. And what if you could also get reviews, price comparisons while you're at it?
