The description of Mike Rutt as the only guy that processes an order rings true.
I've been ordering from him for 7 years and have never had a problem. He doesn't substitute, change prices from the time you order to the time he ships, or any other nefarious trick.
I've always gotten superb service. Couldn't recommend him more except that smokingpipes.com usually offers a better price. It wasn't always that way, but about six months ago he raised his prices somewhat.
His site also has a software mechanism in place that keeps count on availability; so if you order from him and don't get the message "quantity order exceeds inventory," or something to that effect, you can be sure that he has in stock the quantity you ordered.
He also offers GH Dark Plug, perhaps the only vendor in the States that can get it, but it is a will-o-the-wisp tobacco, making only brief appearances.
Mike Rutt and marscigars.com is great!
