I have the opposite problem. I was interested in an 80s Miyata 914, was pumped up about maybe buying it in the $175 range. I first saw it maybe....a month ago? I emailed the seller a couple of times, as he didn't have a phone number there. On Christmas day, he puts up the exact same listing for the exact same bike. Keep in mind that this is two weeks from when I sent him the first email. I think maybe he might have not gotten my first one through the first listing, so I email him again. A week and a half passes, still no response. I have to head back up to school after my winter break, so if he does respond, I'll have to get my dad or a friend to go up there and buy it for me. However, that is assuming that the seller will eventually respond. It's been about a month and about six emails, and still nothing. He won't even respond when I ask if the bike is still for sale (which I asked a couple of days ago).
I have been through the frustrated seller thing before, but never the frustrated buyer. Usually people want to get rid of their stuff and get cash for it.
