As an addictive Emu and Ugg buyer I would recommend that potential buyers check out Amazon.com, Ugg Stop and all the aussie Ugg sites. Even with postage they still work out cheaper. It is also cheaper to buy them from the states as they quote in dollars and its approx half the price in uk pounds. Emu boots are a great alternative to Uggs the only difference being is they can be slightly slimmer in the higher leg boots, but they do last longer.
I hope this is of help as I agree that some sellers are being a little bit greedy or we, the buyers, are being a little bit silly. Spend a bit more time searching and you can save money.
