I have tried sooo many times over the years to buy (mostly computer hardware, printers and mobiles) specials in the Australia Post catalogue, but not once been able to successfully get anything. Always out of stock. In all the close by post shops.
how did everyone else get all the bargains?
You may have to go to the bigger post offices. not the little one in the back of the newsagent.
Phone the 13- number, and they will tell you the nearest post-office with stock.
