Just want to share:
I just came back from Australia. There are in fact a lot of shops selling UGG material but under different brand names. Some made in China (no label), some emphasize made in Australia (really labelled). Those made in Australia are around 40 to 50% more expensiive.
I just bought a pair mid 筒for kid, with butterfly at back- AUD90 which is around hk$500 but obviously Not made in Australia as it is not labelled. Its ok for the little girl and I think its cheap. For those locally made, its like AUD130 to 140.
This morning, i was in Sogo. I found exactly the same I bought, made in Vietnam, selling HK$2,290 ! (OMG!!!!!)
