Back in August, regular commenter poedgirl alerted us to the fact that items on sale in Coles didn't always have unit pricing accurately indicated. It seems Coles might have become more efficient at that process, with specials now correctly showing unit pricing.
The picture above shows how specials involving multiple items should be presented: with the unit pricing both for single purchases and for the bulk purchase. Poedgirl explains:
I took this photo at my local Coles tonight where you can see 5x 1.25L bottles for $5 and below that it has the 80c/L that it should have always had.
Unit pricing should make comparisons easier, so it's good to see it being properly applied. Thanks again Poedgirl!
