The age old question of trusting your gut feeling

I recently emailed a new A-gon member to see about picking up a piece for a friend's father who was interested in putting together a system. I will be in that part of the state tomorrow & could have saved the shipper the hassle of shipping, been able to inspect the merchandise, etc.

I didn't get any kind of response. Not a "It's been sold", nothing. Hmm, here's somebody with no feedback selling an item but doesn't want to communicate.

So the thread is, how many of you have had somewhat similar situations regarding audio? Doesn't have to be net oriented, just a decision based on instinct.
