I got mine from Cynthia at the link posted. Also, I get my hair bands, brushes, combs and other items from her too.

I've also purchased Vellus products from the Woodpeckers people. In fact he told me to call rather than use their website, as the price is better. The phone number on their card is: 1-800-597-6342
