Meat is up and down. I buy mince there - $7 a kilo, it is good quality, lean mince, but you have to buy like 2.5kg minimum. It says on it "use within 24 hours or freeze". I break it down into 500g bags and freeze.

Stuff I regularly buy:
- tissues, toilet paper and nappies - they work out the same price usually as on special at the supermarket but I can't be bothered waiting for the specials, knowing where the specials are, and I love having 148 nappies stashed away
- mince, see above, it is good quality and cheap
- bin liners - best quality I've seen and cheap, 10c each
- kitty litter, much cheaper than supermarkets
- snap lock bags, as above
- oats - super cheap
- canned stuff - tomatoes, chick peas, coconut cream and milk, lentils
- tomato paste
- tinned tuna
- coconut oil (heaps cheaper!)
- coconut flour (also heaps cheaper!)
- batteries

Fresh stuff I tend to buy what is cheap at the time. Pink lady apples in the supermarket are $6 or $7 a kg, they were $4 at Costco. But you have to buy 2.5kg. Four avocados for $12 where in the supermarkets they are $6 each.

Ooh another one of my big ones - bakers flour. 12.5kg for $9, supermarket I was paying $10 for 5kg. Cheaper for more than double the amount.

Lamb roasts were a lot cheaper I noticed today - $8/kg!

The only chicken I've bought was some vacuum sealed bags of chicken breast. They didn't seem too much cheaper, I'll need to find the cheap stuff that Divvy mentioned!

Smoked salmon is heaps cheaper, if that's your thing
