I’ve sold something on eBay and put the postage cost in the description. They haven’t paid yet and I checked it, it showed how much it’s sold for then underneath says postage (free for buyer, you pay) but why is it saying that? Thought maybe I’d made a mistake and forgotten to put the postage cost so checked original listing and I hadn’t, the postage cost is there. So why is it saying I have to pay for postage? I’m so confused!
