Thanks to Eleanor B. for bringing this one to the attention of the community, sorry you got caught, though! This is a tough one to spot, and it's part of a new generation of sites which are trying awfully hard to look like the genuine UGG® Australia site at www.uggaustralia.com. I can't say I blame you for being fooled.
If you're seeking cheap UGG® Australia boots please, please understand that if something is priced like a fake it IS FAKE. There are other sensible rules to follow, but I think that one is far and away the best of them. It's the easiest one to remember and so far as I know, it's infallible.
