Thanks, very interesting. And you're right, vote with your feet. The problem is eBay is world-wide so gives you an huge access to sellers. I think Facebook Market Place is pretty big, but the thing is eBay has a good setup from selling, buying, bidding, paying, posting, listing etc. Not sure any other platforms are that sophisticated. may be cheaper But you've got to weigh that up with potential reaching fewer buyers. But I'm going to have a look at Facebook.
