I recently bought 2 pairs of what I thought were genuine UGG boots. Yes ok the price was to good to be true, but as UGG have changed the design of the sole on this seasons UGG's I thought I was getting clearance stock (fool).
Any way the site to steer clear of is UGGSALEF . It looks like a genuie site. They will happily contact you regarding delivery queries you may have but should you want to return the goods or require a refund they choose not to answer any e-mails.
Hope this helps.
