ceo/director buying another positive signal today with the ceo/director reporting that he has purchased more shares in the last few days.
also whilst not directly related was happy to read in todays financial review that woolies and coles are looking at RFID to improve supply chain efficiencies along with BHP,visy and linfox.
hopefully indicates a growing industry
still a lot to do but looking good I feel
any other thoughts or comments ?
