I consider some of the PMs as trash/spam mail and use the delete.If someone is serious they are usually direct in their PMs and replys and don't beat around the bush ,anything less is trash mail. The vulthures that circle my ads and low ball I just ignore until they get serious.
On the other hand some of the package deals are beyond the reach of some and others have items of interest but the package deal is to much stuff. I usually price a package deal by item but add a package price if they want it all.
deacon. they are not real offers with out a price just seing what their stuff is worth, I figure they are not serious, again trash/spam.
Thing I hate worst is someone highjacking a post.
