If you download a few bytes over the internet you expect this to be cheaper than having a heavy physical entity delivered to your door by a whole logistics operation, but Amazon seems hell bent on disproving this.
I'm seeing physical books costing a third of their digital equivalents on a regular basis, and all it's doing is stopping me from buying anything at all from Amazon. Today, for the first time, I've downloaded Apple's iBook app.
Indeed, I've now decided to stop using the Amazon service at all because of this price gouging.
In the internet world, where prices are transparent, how stupid can you get about ripping off your customers?
