I don't use eay, but this sounds like a non sustainable business model...
The problem is, the Chinese sellers (you'll spot them easy--item location, 10 cent start price, $300 shipping...) are so numerous, eBay can get away with it. Also, for a professional/"Power" seller, someone doing hundreds of listings, the numbers even out. Ebay isn't really friendly to small/one-off sellers any more either.
I still use them for items I can't put on etsy (which in fairness needs a credit card and bank account, too) because they get way more traffic than I could hope for on a private site and they're good for things like specialty collectibles. I won't sell specialty sports items (ballroom gowns--one of those is why I no longer accept returns) or high-dollar start values there any more.
The only problem with FB groups is a lot of people want to send a check (hahah, not happening), want to lowball you, and you have to weed through the millions of posts of people asking for tons of stuff or even a horse for free/next to nothing because of xyz sob story.
I've bought a couple things that were a steal (I paid asking price and shipping), but the one time I tried to sell some chaps, I got lowballs and then the buyer magically had some vet emergency and couldn't get them until she got paid again...and disappeared. Meh.
But yeah, eBay has gotten weird and I avoid avoid avoid. When I was looking for saddles, I used allofcraigs.com.
Not to hijack this thread, but I noticed that there are people randomly "disliking" certain posts here. It's kind of petty considering many of the ones that get the thumbs down are neutral statements as the one that Tarheel made. I hope the mods gets rid of the thumbs down thing on this site.
