I buy stuff on ebay regularly and wanted to sell a couple of items.  I hadn't actually thought about the fees  because I naively thought they would be reasonable.  So I checked and found out it is 13.4%, pretty outrageous.

It is especially weird when ebay has a significant stake in (and used to own) gumtree, where I can list for free.

No wonder people sell on gumtree rather than ebay these days.
