Why do some retailers sell UGGs but don’t bear the UGG label?

Cream Natural Classic Cardy UGG Boots

Local reputable shoe stores may have sale seasons. Many of these stores may sell UGGs at a discount. For some people though, it is definitely more convenient to buy discounted UGG boots online. Many reputable sites also go on sale during off seasons.
Auction sites are also great sources for discounted UGG boots. The really cheap UGGs are almost always second hand pairs. You probably cannot buy authentic brand new UGGs from online auctions. Very low prices on seemingly authentic new UGGs are a definite sign that they are most likely fakes.
