If you already know how and where to get those stuff that's great. But for most people, they just want a quality product at a reasonable price with out much thinking or research. Amazon is full of fake Apple/Samsung cables and chargers or no-name brands that might fry my phone or start a fire. So I am paying for the convenience but it is at the price I'm willing to pay because I'v been burned (not literally yet) too many times trying to be cheap..
