Why would a seller do this?
Ok, so before I bought my last 2 machines I had made an offer on a Damascus treadle. She has photos of the machine and all the attachments and the manual was included. So today she emails me back and counter offers 10.00 more than what I offered, however she says "you can have all the attachments but I'll keep instruction manual." Why would a seller do that, when the ad already shows photos of it and included it in the original sale?
