Its not a problem however I find that with eBay, and I assume the non-personal nature and somewhat anonymity of email, that the number of dumb questions and the severity of them more than triples over what one would get in a 'one-on-one' situation.
I had responded to the person's question and will likely be selling the individual something completely different than what he was looking at on the eBay listing that I had.
If I had a car dealership and someone said they would purchase a car I had if I threw in a CD player, that would be an acceptable request, but to ask me to build them a garage would be a very stupid request.
This guy's question was a very stupid request.
I have also learned than with about 50% of the stupid requests that I get come about 50% of my problem customers, so I tread a little more cuatiously with these ones.
