Should you trust auwigsale.com? No, not at all. This is a chinese fake site and simply fraud.
auwigsale.com seems to offers a lot of high quality wigs from major brands, but actually it sells cheap chinese wigs. They have NOTHING to do with the wig shown on the website.
The site implies that the company is located in Australia, but you will not find an address or a phone number, because it is a chinese company.
