Saw this advertised on tv.
Spend $100 or more and reserve a delivery time for a Wednesday and get free delivery.
To any customer old or new.
From what I can tell this is a standard offer with no expiry at this stage.
Coles have redesigned their website to be more mobile friendly now too.
"Offer valid at Coles online for customers when they spend $100 or more, excluding Tobacco products. Free Delivery excludes Hamilton Island & Remote Orders and will automatically be deducted at checkout. Normal delivery terms and conditions apply."
Seems like a pretty good deal.
The main reason I prefer to shop at Coles online is because you can buy bakery items from there.
Woolworths force you to buy the mass produced homebrand/wonder white etc bread if you buy online.
