Massive difference in the price of these two identical products - the first one seems to be a Priceline's home brand. The second one is not available in Priceline but it's promoted by Chemist Warehouse (doesn't look like their homebrand through).

Is there any difference in quality etc that would justify the price difference? Which one would you go for? Any advice from pharmacists would be appreciated too.
Vit D3 is obviously an example in this case - the question is much broader as this type of price difference is often seen across different supplements etc within one store or across both competing stores. Options in Coles and Woolies are generally more expensive, even at their half price promo.
The more known, expensive brand. They are more effective even if the ingredients are the same.
