No motive behind this question other than boredom and the question popped into my mind. Absolutely nothing to do with my own three unrequited ads!
I was just curious how often people place Wanted ads but never manage to find the item they're after. Looking back at my own history in the classifieds reveals that I have quite a few "Not required" items. It seems that several of these are multiple attempts at different times to find something then I give up when it's unsuccessful (case in point being my current quest for a ZenithStar 80 FD, which has been going on for years!).
What do others do when you can't find what you're after? Buy new? Try something else? Give up and try again later?
