We all love a good bargain, and judging by the legions of shoppers last time I was in there, more and more ladies are going the DIY hair color route. That said, one of my faves is Sally Beauty Supply. For only $5 a year you can buy at pro prices, and I just got two loyalty $5 gift certificates for my renewal. In addition, spend $25 in any month and get 15% off the next month. I buy all my color and their generic brand of shampoos is as good as the salon brand for about a quarter the price. Visit their site here and shop online if there isn't a store near you.
