When you're out in towns/cities and the kids are being good and they want a treat, I go into Coles/Woolies/IGA etc and buy a pack of 6 ice creams for about $6, rather than buying from the convenience stores at $3 each!, We also have a small esky and make ham + salad sandwich/wraps most days when we're out. If I go to café with the family for lunch we normally eat less and still pay $50+ compared to healthy cheap wraps for probably $10. But you have to eat out sometimes, so enjoy it when you do.
