I like the Question and Answer option. I can check out the seller. Anything other than a straight answer (including no answer at all) and I head for the door. There are several items i would have purchased if I had gotten an honest answer.

I've had people give me information on my listings (which I then updated) and I thanked them for sharing their expertise. We've had people ask about combined shipping (and yes, they did buy the items). I think in some cases people just wanted to be sure we were really here.
