Why do Hair Magazines cost so much? Not the cheap ones in the drugstores and Walmarts.?

Because they are specialty magazines designed for professionals. Because of that, the circulation is lower, while the costs are probably higher due to the better quality of paper used. For professional stylists, the price can be deducted on their income tax since it's business related.Why do Hair Magazines cost so much? Not the cheap ones in the drugstores and Walmarts.?
