Don't know if this is the appropriate place for this mini rant, but why not?
I actually appreciate people who save otherwise serviceable bikes from the dump. And I appreciate people who check over the mechanicals, replace worn parts, clean bikes up, then look to make a profit off their labor. And I realize that there is nothing wrong, per se, with flipping.
I actually saw the initial add and thought, that looks like, with a once over, maybe a tune up would make a nice commuter, or entry level bike for someone. Oddly enough, that same bike sat on CL for weeks until the seller dropped the price to $100. I know the original seller sold the bike Friday because I actually inquired about it, seller texted me back that he just sold the bike. No big deal, as an extra bike project is more a want than a need for me anyhow. Now the same bike is back up with a different seller for $250.
So here is add A, posted Friday.

Here is add B, posted this morning.

So, I am not hopping mad, nor even disappointed I didn't rush out and get this bike, but mildly piqued.
