Yes on line I have, I didn't have a car and it was the middle of winter.
I must say they were great how it all arrived, very professional and I used one of the 2 main supermarkets.Everything was there...and all well packet, and the guy was very polite.
If I had too again, I sure would...it's not expensive, and really if you need food that is a brilliant way to shop.
PLUS: Coles now have a ''click and collect''.
You shop on line, and by a certain time your shopping is done! you go to a special area, and collect your food.(see my pic)
How amazing is that!
