Agree with the sentiment but, purely from personal experience, I really don't like submitting my details for every retailer I might buy stuff from. Not so much from a security pov but all the hoops I have to jump through like creating a username and password that's actually accepted first time, and so on. I've gotten to the stage now where I won't buy from another retailer where I have to create another account, if at all possible. As consequence my online purchase history (aside from grocery shopping) for the past 3 years is almost exclusively amazon. If I were a retailer I would be looking to make the buying process as slick and seamless as possible and, alas, amazon can provide me with a solution.
