Veniards only sell wholesale to the trade. I'll make enquiries for you, but with recent increase in postage charges here the price will double on a single pot! Sending a pot of "mud" (Tippet degreasant) went up from ?0.90 to ?3.00 just to give you an idea, and that's just domestic. The dyes are about ?4.50 each (about $6.75), but you will need to be ordering quite a few to make it worth while.
Stop press. Just spoken with a contact who has a Veniards account. He may be able to help. I'll PM you.
