Aldi

Good source of very reasonable packet and shelf goods - including household staples, vegemite, cornflakes and baby products plus well priced meat and veg and dairy

Pretty good variety, the value is amazing-compared to other supermarkets this is very, very inexpensive. Lines at the checkout can get long at times, but apart from this, if you're happy to try mostly "Aldi" brands, you'll save a lot of money.
