If there were to be a real life “easy button”, I’d nominate Amazon’s Prime service in a heartbeat. Bear with me as I sing Amazon's praises briefly.  By saving users' payment information, order history, and providing short delivery time, Amazon transforms what could be a complex shopping process into a simple click of a button - leaving users saying, “Well, that was easy." Yet even better than the service itself, is how the service makes people feel.  Amazon Prime allows users to spend the least amount of time for the largest reward, trusting that their package will be delivered efficiently and on time.
