RE: TROLLS?
I had the very same thing happen. I was selling a plane,and not list the shipping price because I didn't know where it would be shipped too. I got about 10 replies asking about shipping to here and there. I did respond to the first 3 or 4, then said this isn't worth my time looking up each state zip code and shipping costs. I kept getting emails on questions on shipping. So, what I did is not respond to those emails, let the ad expire, relisted and stated $90.00 shipping. Never heard another word. Still have the planes.
People don't want to pay the rediclious shipping charges, and I can't blame them at all.
