Lol, go easy on the OP. Its obvious that he had no clue what they were talking about with they said key, etc. So, he didn't even know what to look for. Anyways, at first I was going to require everyone use PGP/GPG but really, it only protects the buyer. So as a seller, yes, I would prefer everything done in PGP but when its all said and done, it really doesn't effect me if the buyer uses it or not. Its not my address thats going unencyrpted. So,yes, I am going to recommend it, but if they dont want to use it, or take the time to use it, then thats up to them. its their choice....
