+1 on wigs.com. Good quality wigs are expensive, and currently they are having a half price sale on wigs by Louis Ferre. Louis Ferre wigs range from good quality synthetic to really stunning human hair, and there are some insane deals available there right now. I just got my first one from there and I am very happy with it.
So if you are down on your dough (as the Village People say) or are just greedy and want to try a few different hair colors, and/or really don't want to walk into a wig salon, then go check out the sale. After all, what girl can resist a half price sale on some quality merchandise?
The sale is on through the end of October, and if I can scrape up a few more clams, then I am going to try going blonde.
