Joules is very strict on who sales their brand..They will not even accept order on their own website if they think it is an order larger that what can be assumed for personal use...
They do have this link at the bottom of the page:
Personal Use - Each order is for your personal, non-commercial use. Resale of any Joules product without the express, written consent of Joules is strictly prohibited. Multiple orders representing what Joules deems to be commercial quantities will not be accepted via our direct shopping channels.
