The extension really doesn’t do it any favors? Maybe better trying to sell at the build up to either large football event, world cup etc or start of the football season...
Try the large manufactures, sports outlets etc at 1 - 2 k (they can only say no or nothing...) to some that might sound mad but if you valued at hundred they might think it’s so cheap it’s not worth having…? Otherwise reseller I don’t think would buy it… Without a high listing etc (so much easier said than done) it’s an all or nothing type domain...
