Definitely Amazon is one of the best around. I've even written a complimentary letter on PFB to them, when I ordered an item late at night on a Thursday, and received delivery on Monday. I've had nothing but positive things to say about them with every single item I've ever ordered.

Also highly recommended: QVC (qvc.com). Those 3 letters stand for Quality, Value, and Convenience, and trust me, they live up to every single one of them. I have yet to find a single company which even comes close to them in customer service. This was another company that delivered an item to my house just a few days after my order. Additionally, the quality of their merchandise is 100% guaranteed.
