Quite frankly, I don't know what you folks could do to improve your service. I do a fair amount of on-line shopping and there is absolutely no one else out there who even comes close to offering the quality and the value of a product, along with the shipping speed (and subsequent fast delivery) that is offered consistently by Zappos.com. I can only advise you to just keep on doing what you've been doing. Sincerely, Doug W.
