I noticed these were on discount. They're fantastic for storing all the tiny things you never knew you needed but ordered anyway after seeing on OzBargain and now don't have a place for. Works out to be $15.03 including GST. They're claiming it's 55% off in the catalog

Free shipping kicks in at $45 GST exclusive. So you could get three of these and a few CR2032 cells to pad out the order for free shipping.

I've also had decent experience putting 'Authority to leave at xyz' as part of the address so that Toll courier don't waste time with the card, but you'll weigh that against the risks at your specific delivery location.
Others have also mentioned that you can get to free shipping pretty quickly with a single-board computer like the Raspberry Pi or a BeagleBone.
Must be stock issues on something else you ordered?
