The cartridge arrived on 07/09 so two days before the estimated date. No problem then. As against it was not in its original box, the nude in a bubble bag envelope is not marked expiration. I wrote an email to the seller who replied by return "mail": "The ink cartridge is brand new and direct from HP that we are official HP partner if the expiration date must be nt until the end of 2014". (This is a copy-paste of the answer.) I therefore expect that my cartridge is completely empty to unpack it and I will find normally the expiration date on the cartridge itself !!!
