I'm sorry that this doesn't answer your question but at least it might help you avoid the numerous fake products which are on offer:
When you find a website advertising (allegedly) genuine Ugg boots, you should always enter the web address into the search facility here:
http://www.uggaustral...ucation,en_GB,pg.html
That will tell you whether the site is an authorised retailer of Ugg boots, or not.
To quote from my link above, Boxtops:
"Be cautious of purchasing what are advertised as UGG products on eBay, and other auction websites, including Tao Bao and Craig’s List. Authorized UGG Australia retailers are not permitted to sell products on eBay trade boards, therefore the UGG products on auction sites are often counterfeit. However, many counterfeiters are now charging full retail price to avoid detection from consumers"
That is helpful, thanks chris. I know there are so many fakes out there and when you are spending that much on some shoes I want to know they are the real deal.
