Is the inventory commingled, are the sellers better vetted, is it obvious that you are buying from a 3rd party and not Walmart, all that I don't know. Just pointing this out.

I regularly buy from a small website that isn't run by Amazon - some months after every order I get a different credit card in the mail because someone hacked the small website. They really need to give up on running their own secure payment processor and hire someone bigger. (I order from them because for the obscure parts my car needs they have the right one in stock and know which are right)
Amazon has the infrastructure to deliver anywhere in the US in a reasonable time and their size allows them to offset that guy in the Oregon woods ordering a pair of socks with a Manhattanite hipster ordering a $1500 coffeemaker.
