Is this a legit website?

The site looks legit. That being said, I would doublecheck by going to the Uggs official site and make sure this is a site that has actual Uggs and aren't just dropshipping some junk from China. Another tip is to see if it says "imported" and then contact the site and ask where the product is imported from. Just ran into a site that looked great and then the boots ordered were actually junk from China, they are just a dropshipper selling cheap crap, so it is a concern.
