A3)  What are the requirements to become a distributor?

We have strived to make this process as trouble free as possible.  Simply put, we do not require a minimum order or stocking.  However, we may ask that you provide a copy of your business license or resale certificate of exemption (sales tax exemption).  We reserve the right to refuse a request to become a distributor for any reason.  Although much of the USA and Canada are available for the addition of distributors, there are some geographical areas where it would be undesirable for us to add another distributor.  We value our existing distributors as well as prospective distributors.  Please click here for additional information.
