Why's that? What has changed that makes selling nicknacks on Ebay less worth it?

I never found selling cheapish knicknacks on Ebay very attractive financially but it seems like it's less of Ebay's business these days and just not something I'm willing to devote a lot of time and energy to.

More generally, I do think it used to be more of a flea market even if I never found it a great selling platform for cheap items.

Unless it’s your business, or it’s high value items, the dollar per hour is pitiful.

$10 item sells for $9, charge and ship it, eBay takes its cut, barf. Garage sale or just donate would be simpler.
