A thank you by a vendor is just great PR, and appreciated by most, myself included. I have no problem with that at all. It shows 2 thing, IMO.
One is that you got the order, and 2, you appreciate the customer enough to send a message, even if it's automated.
BUT if that vendor starts to send emails every couple or three weeks, and in them, provides links that knocks other people, vendors, cuemakers, FORUMS, Members of said forums....etc....then its a different matter, IMO.. The above referenced, but not to be mentioned, idiot, tends to go overboard with that crap...considering his own storied past/not so past issues with the law and other members here and in other forums (stamp collecting , I believe). Not to mention he likes to threaten not just legal action but physical action too....
He's just a simple, name calling, dirtbag....nothing more needs to be said

(now I await his email of lawsuit threats to take everything I own...hope he likes my ex-wife.....and the cardboard house he says I own....I only rent it...hehehe)
