I buy mine at zappos! no tax and free shipping :) also try eBay if its new and the seller had good reviews. I bought a pair on there and love them! just be sure, and lean towards ones you can return just in case
Ugg is too expensive -_- i know zappos had collected many good brands shoes.you can go to see . but i highly recommend this fashion site http://www.mixmoss.com/shoes-boots-c-110_139/ .price is ok,design and quality is also no problem .so good luck.
