This seems to be a pilot scheme but if it comes to fruition I’m thinking that it’ll be exploited by people returning things because they don’t fit or have changed their minds etc....I’ve already had a couple of buyers nit-pick for the most minor of faults (on a preloved item!) in order to get a refund.
I try to sell elsewhere now because of the risk of being caught out by dishonest buyers exploiting the returns process and extortionate selling fees. I think if this comes to fruition I won’t be using eBay as a seller anymore.
