Dumb comments like Whysnow's are the reason to uncheck the "Forum topic" box when posting in the Martketplace. There's no need for asinine comments from a Pinsider who isn't even a potential buyer. Potential buyers will send a PM if interested and the deal will go smoothly from there in private.
Every time I've allowed forum comments, there's always some dickhead with a stupid comment or someone commenting on the price.
