When I was a new teacher, there was a lady that came after school sometimes and took orders. I remember her because she was so funny, but the thing she always said if you said you didn't need anything was, "It's what you need in life that makes you happy, it's what you want!" I don't know how selling it works, but there was never any pressure to buy. I don't think it's set up like a club with minimum requirements, but it may have changed.
