This is not a little difference of the price, this is a BIG difference of the price.
Here's another comparison to make from their website today.
Dick Smith Alkaline D batteries 2 pack $6.98
Energiser Max D Alkaline batteries 2 pack $6.98
Maybe DS batteries are OK but I would always expect home brand to be cheaper than a recognised international brand like Energiser. Whatever were they thinking!
