Zappos is one of the most successful online sellers of shoes, but what they really shine in is service. So it is no surprise that they sell more than shoes. Clothing, bags and other accessories are now available.

But my favorite category is the eco-friendly category. There are shoes made from recycled rubber and shipped in recycled packaging, bamboo shirts, organic cotton dresses, recycled plastic backpacks, even "vegetarian" non-leather, animal-friendly shoes. Available, of course, at zappos.com.
