Funny you should start this thread when I've just had my very first bad cl experience. I guess I've been lucky up until now. This guy posted a Trek 370 race series for 75 bucks. I called him and asked when I could see it. He said after 6pm would be fine. (this was 2 days ago) At around 4:30 I emailed him to touch base and asked where he was located. Nothing...6pm...nothing...7pm...nothing...I emailed him again to see if they were still for sale...nothing...I guess since I jumped right on the add within an hour of him putting it up, he figured he was letting it go too cheap, so he'd just ignore me. I'll bet he re-post it in a few weeks at 150...asshat.
