I've been buying from Woolworths every Wednesday, if my order exceed $30 shippping is discounted to zero. I don't know why I can enjoy this general discount, because their website only offer shipping reduction on much larger purchases. This Wednesday I put $150 and still have to pay for shipping (using same account of course), so what changed? (I'll turn to Coles if Woolworth doesn't offer free shipping on $150 order.)
Thanks!

Probably cause they introduced "Delivery Saver" see on that page above… like a subscription service but for deliveries.
I think Dan Murphy is also doing the same thing now too.
