Personally I only ever buy things when they're half price so for me buying ColesWorth home brands happens when the other brands are not on sale.
That being said, I have noticed that most times the home brands are still cheaper than the other brands at half price.
What do you usually do?
Depends what products. Some of them are quite obviously made in the same factory as the branded stuff with the same product, same jars/packaging, nutritional information, expiry dates etc. Would be smart to opt for the cheaper choice. Other products, maybe not so much the same quality or added value.
