Toppik has a deal where you can get the big bottle for $35 instead of $40. All you have to do is have them bill your credit card automaically every few months--kind of like a subscription. I like it because I save a little money, and I don't have to remember to re-order the product. Another Toppik tip...when you use Toppik, you probably won't have to wash your hair as often. I used to wash my hair everyday. I was concerned that if I continued to do that with Toppik, I would run out right away, so I decided to just add a little Toppik to my hair everyday. With this method, I only have to wash my hair once a week--it never looks dirty. I am able to save a lot of time in the bathroom and I never run out of the product before they send me more. Good luck.
