Palmolive Dishwashing Liquid 4x750ml $11 ($9.92 S&S) + Delivery ($0 with Prime/ $39 Spend) @ Amazon AU
Minimum showing as 5 for me. How did you get 4 OP?
Try the Original.
I still find $0.99 coles/Woolworths homebrand dishwashing liquid cheaper
Probably because you haven't used one of these yet. (I was same as you, always bought those homebrand ones but not anymore )
Good price w/ s&s but its effectiveness might not be as good as other brands. I believe this is the direct link to the bottle's ranking.
