I got free samples too. I really like Biogroom. Check out
www.kvvet.com you can get the shampoo and conditioners 12 oz. for like 6 bucks.
I don't know if they have all biogroom products but, but thats about 1/2 the cost that i have seen at other sites. (we don't live near any pet supply stores that sell it, so I have to order about everything we use online).
