This article got one thing wrong; "eBay's fees can be kind of a rip off" should be "eBay's fees ARE a huge rip off". That combined with the removal of negative feedback for buyers is why you should try Amazon rather than sell as an individual on eBay.
But only if you're in the US right? I'm sick of eBay too, but they bought the "Australian" Gumtree trading site as well so there's really no alternatives.
True, somehow sellers in China can get by selling items to the US for less than a buck on eBay, shipping included. I never understood how this worked. Just mailing the same little item within the US would be like 2 bucks, plus eBay fees.
The postage thing was explained a while ago somewhere, possibly HN: there's no "settlement" between international postage services in the normal sense, and there's a HK postal service that will ship to the US for pennies. Once it arrives in the US postal service, it's their cost to deliver it.
