Chances are, whatever coffee shop, restaurant or store you are at in your defence posting location, you may be talking to a serving members dependant, possibly someone ex defence themselves. When making an order or getting assistance ask if they offer defence discount. You will be pleasantly surprised how many will oblige you with something, many will give you their staff discount.
Woolworths competitors have their own rewards system, but it’s not even close.
It’s worth having flybuys for those days you just want to pick up something quick at the local Coles store, Kmart or going to Bunnings for new patio furniture or grass seed. You’ll get $10 off here and there if your points don’t expire before use.
(I do check Coles and others latest offers for value often, at time of writing I could not find any that last over a long period. Should any long term Lats know of any, please contact me with your hack to maximise value over a 12 month period and I will investigate it and edit page)
