Interesting timing: I just got an e-mail for a (free) app that I purchased in the Amazon app store. Only problem, I have never visited the Amazon app store. The Amazon rep on the live chat explains to me that this is because someone entered their e-mail address incorrectly when making a purchase. How does that make sense? Shouldn&#x27;t you need to be signed in to your Amazon account (or some other account) to make an app purchase? It actually makes you type in your confirmation e-mail address manually? Can someone with experience in their app store comment? That seems like a brutal design decision...
