One of my main reasons to go with Amazon, is how trustworthy their service is. Package lost? They send another one free. Package delayed too long? Get a refund (and keep the package when it arrives). Don't like the product? Return it for free. There's never any friction, even in the bad scenarios. Combined with the fact that they consistently have the lowest price, it's hard to argue in favour of other services.
