I worked at a well known australian Smallgoods company a few years ago, who did most of the cold meat and hot dogs for Aldi. All product was exactly the same, with an Aldi label instead.....most of Aldi Products are like this. They are also the MOST most strictest companies to supply food too as well as far as quality goes, far above Safeway and Woollies etc.
I love the nappies and wipes more than any other brand!
The Soap is great.
I love the $1.49 liquid Laundry stuff, and have used it for YEARS. (I didn't like the powder one as much though)
I love the Yoghurt.
The Cheese is brilliant.
Chicken products are brilliant!
Flour, Sugar excellent value, bigger sizes.
Cereals, excellent value.
All biscuits etc and YUMMY and cheap.
Kids love their brand "Shapes" biccies, Sultanas and tinned fruit.
Bread is great, only problem I have had is when I have tried to purchase the Turkish Bread...on occasions it has had mould in it, but that was a few years ago now.
Rice is fantastic, same with Tomato paste, spag sauce...

The only let down for us is some of the beef products (a bit tough), and a small portion of the cleaning products.
I love the Diswasher stuff, and dishwashing liquid, Toilet Cleaner, disenfectant, sponges etc etc, but the Spray n Wipe Stuff and Shower Cleaner stuff is not great...

Occasionally Fruit & Veg can be not great, but they always have a couple of items super cheap, so if you can base your meals/lunches around these items for a week you are going great.

You will notice that Coles have tried to match them on prices for things like Coles brand baby wipes, Laundry liquid etc, but the quality is NO WHERE near as good as Aldi.
