Yes ebay cannot believe that for many years sellers have managed to work out their own postage, without being told they must use simple postage which is far from simple. Seems to me it is a good way for sellers to lose money and ebay to make profits.
Just like the buyer protection scam, unless buyers and sellers are fully aware, buyers are paying for nothing and sellers are again at risk of losing money.
I think my days of using ebay are coming to an end soon, no activity for a week, so the sell for free is a joke, I have experimented with promotions but why should that be necessary if it is free to sell.
