You're right, RM.  In addition to possibly being seen as spamming or review-begging, it tends to make some think you're less successful than you are.

When I was a kid my father and I watched football every Sunday.  Sometimes a player would score a touchdown and freak out, dancing, pointing his finger, taunting, etc...  My father would say to me, "Son, remember what I'm telling you.  When you get to the end zone, act like you've been there before."  Then Barry Sanders came along and demonstrated such class.  In my opinion, he was the best running back ever.  Each time he scored, he simply handed the ball to the ref and walked off the field.  He acted like he'd been there before and would be there again.

Many years and hundreds of Poser purchases later, I received a thank you letter from a merchant.  Part of me was pleased to be thanked.  But, another part of me was like, "I've never been thanked by a merchant before.  Is this merchant not used to getting sales?  Do they think I might be their last sale?"

My point, in addition to RM's point, is that merchant thank you letters are a double-edged sword.
