A long, LONG time ago, my mom asked me to sell her old manual typewriter from her college days. It sat around for a very, VERY long time. Finally, it got to where that was the ONLY thing I had left to list, and I had no money to buy anymore inventory. I gave it a half-hearted cleaning and listed it. Completed and current prices were all over the place, so I just slapped a stupid-high price on it with best offer, just to see what happened. I priced it at $199.99 or best offer (plus shipping).
There wasn't a whole lot of interest in it, but finally the other day I got a $75 offer on it. I asked my mom if she was happy with that and she said no, not really, so I countered with $150. Last night, the buyer countered with $100, which my mom was happy with - especially once I researched and saw that the highest price that this same typewriter got recently was only $35! I don't know what made this one fetch a higher price, other than the fact that I asked for more.
