HAHAHA!!! OMG I have to laugh about this because I bought some yesterday for my teenager (non-grey) for her arthritis and her travel anxiety. I didn't do research ahead of time as far as pricing but was pointed to our local Doggy Daycare that sells it. I went in and talked to the guy and decided what would be easiest for me to administer... 1 OZ FOR $99 which is a one months worth of doses Let me tell you - there's a sucker born every minute and I am apparently one of them - SHEESH.
Anyway - what's done is done and if it works well I'll be comparing the brands in this thread.
