No offense, but I think the problem comes when people hope to sell things to make an income. This is why eBay s*cks now. Personally, I want to get rid of things I no longer use, but get a couple bucks for it instead of goodwill. You can take the time, effort and gas to drive to a donation place to have them not be open, busy, refuse, etc.
If I can get a couple bucks for something I no longer want, I might be able to get a new-to-me used item I have been needing. I don’t care what happens to something after I sell it. I just want to get it a new home instead of the landfill or the hassle of goodwill - and get a little something in exchange. This is what used to make eBay fun...finding a new love out of someone else’s cast offs for garage sale prices. But then sellers and stores took it over and its no different than any other store...except its more risky.
Look, the stuff is out of the box and used, you can’t expect to get anything what you paid for it. Who knows where its been? If its a practically new bigger ticket item, I will ask half. Anything else just chump change.
