I have a 12TB WD external hard drive with box and everything that was purchased earlier in the year around April from JBHiFi in Australia. I don't have the receipt but I could try to get a copy if required by emailing them.

Used it for couple of large copies and sitting idle since then. 

Looking to get 450 but negotiable, I believe I have paid 500 AUD when buying. 

Pick up in Flat Bush or Ellerslie during working hours.
