I had a great experience with wigs.com. They are very easy to deal with. The first wig I bought was beautiful but it wasn't for me, so I returned it for a full refund. Then I bought another wig from them which is just right.
Mistakenly I bought a second wig from www.wig.com, not www.wigs.com. Dealing with wig.com (Paula Young) was a bad experience and I won't buy from them again.
