Pretty much everything JeffS said can be echoed by me. Neither one of us seems to have the kind of items that would sell well elsewhere.
I have a couple items listed on a couple other sites...it's been so long already I almost forgot about them. NO action. Not even many views. Good thing it was free to list...
On the other hand, I'm doing ok on Ebay. I still think their FB policy and fee increases stink but that won't stop me from listing. And tho I participated in the first boycott, I will not be able to in the next one. I have to get rid of my stuff somewhere, and Ebay is the only place with the buyer market.
