This site is absolutely amazing when it comes to every aspect of shopping online.
Free shipping both ways so I don't hesitate to order something when I'm not absolutely sure about the fit.
I always, always, get my merchandise on time if not early! How amazing is that.
Their Customer Service is also extraordinary. Something I think is sorely lacking today. They send emails to advise you of Order Receipt, ship date, etc, so you don't think your order fell into a black hole and no one is paying any attention.
And the Website is attractive, informative, and easy to use. More positive facets than there's room for here.
Shop Zappos for your shoes. There's no downside.
