I'd give it a couple of weeks start to finish. (RG posted earlier saying that he was having problems with the site/posts, so he may not have seen yours yet.)
I think it took a couple of weeks from placing a phone order to receiving my HW orders. Certainly not as fast as a lot of stuff I order, but I try to keep in mind that a) all of the HW stuff is made fresh and has to be capped, counted out and bagged, after the order, whereas other stuff I get elsewhere like a bottle of supplements or iodine just has to be packed and shipped; and, b) most important, this is a very small, family-operated business in which a close family member was recently very ill, so they are probably a little backed up.
I hope this does not sound like I am jumping you -- just offering my experience and knowledge with HW and with what has happened specifically most recently. I am chronically impatient and what calmed me in this instance was remembering that my parasites, unfortunately, are not going anywhere!
It'll get there, and I hope your pet does not have worms because mine did, and it provided for some of the most revolting moments of my whole life (and I have been around the block a few times!). Think live spaghetti...
