I've found that smaller items don't net you very much on eBay, especially if you offer free shipping (which helps your sales a lot). I recently netted $13 for a $25 chainring, and $17 for a $30 bottom bracket. I was happy to be rid of the parts -- and it was an easy way to make 30 bucks -- but CL, FB, or NextDoor nets you 100% of your asking price. But with those, you've got to have the patience for arranging a meeting time and place, and you deal with a lot of time wasters and tire kickers. So you either pay with your money or your time, I guess.
