Sometimes vendors got hot on a forum. I used to be on another forum when Mars, Boswell and Bosi were all the rage. Someone would get a Boswell pipe, then someone else would, then they'd post how fabulous the pipes were, etc. But the hubbub passed.
As said, don't call Mike Rutt, use email. He doesn't answer the phone but is prompt with email. He gets Dark Plug as a favor from someone in the distribution network, but I've never heard that he can get anything else not distributed in the US. I asked him specifically about Dark Plug Rose Geranium, and he said one word, "no."
