Theres nothing worse then no shipping charges at all listed. Usually I just pass on those auctions unless it's something that really interests me. Then I send a "ask the seller a question" email and see if they respond. Some do, and some dont. Most of the time, I dont get an answer either because because the auction ends and they figure there's no point or they just dont check thier email, or they just dont want to be bothered.

What really makes me laugh is when they are selling a single chip and I ask about shipping, and they email me back and want my zip code. I had one, that would only send by priority mail at $3.95 not including insurance. The auction was for a NCV "C" chip! Needless to say, I passed on the auction.
