I think it's the season. Garages and sheds have been cleaned, items donated, and yard sales were held. I noticed that few bikes appear of Craigslist and those that do get listed seem to move slowly.
I bought a couple "winter project" bicycles. But it's been so cold/wet this summer that I've had enough free time.... I've already finished fixing them up. I plan on reselling at least one of them but had held out on listing ether on CL until demand for bicycles increase in the spring.
