eBay Germany have re-introduced mutual feedback withdrawal in limited circumstances. Sellers can request buyers retract neutral or negative feedback within 30 days of the feedback being left.
There are limits of two requests per month, and sellers can only make one request per transaction. Once a request has been made a buyer has 7 days to respond, if they refuse, fail to respond within 7 days, or simply ignore the request then the feedback will remain on the sellers profile.
This is currently available only on eBay Germany and is running as a pilot so details may be tweaked in the future. Mutual feedback withdrawal should however roll out across all eBay sites in a similar format by October. It’s a great move as it gives a seller a real incentive to look after their customers and resolve any issues even if a buyer leaves feedback in haste.
