It's the time wasters that get me. I have learned to just filter them out as best I can. If a possible buyer cannot communicate at some sort of basic level then adios. I have had contact with sellers that are time wasters as well. They list an item without much detail. I ask a few questions about the item, like what is the top tube length on that frame. The response is: the saddle is almost new. Arrrgghhhh.
