Where were you when I was a young single guy ..... ???
You've a great excuse to visit the lollie shop .... you're stocking up for Xmas , Boxing Day and New Year ..

.. and if you've got kids, even better

, no one will bat an eye if you've kids in tow.
I've just stocked up on lollies , chips (big!!! bags) , twisties , chocs , drinks (coke, fanta, mountain dew, solo) , pavlova , cliks , cheeze , crackers , Nobbies Nuts).
My wife reckons I've gone overboard (we don't know if jr will show up this year).
Just the ham , and a couple of 1kg turkey preseasoned rolls (a steggles breast meat and a dark meat) , been getting these rather than a bird the last few years , better value - all meat !!! , but usually go for the 2kg size which feeds the 3 of us , and gives up cold meat to share over the next week or so.
We tend just to graze Xmas - New Year , what we don't eat or drink will keep , can alway do with drinks and the chippies and crackers and cliks and cheeze (if they survive Xmas and New Year will be polished off in Australia Day or if we get kiddy visitors.)
Maybe some local prawns too and a couple bottles of red an white wine .... local stuff sounds the go from what others say.
Those end slab cuts off leg ham (about 3" thick) at Woolies are great value too .... think they are about 3kg or 4kg , a full leg is too much for us , and those small hams are too small and not as nice.
