There have been a lot of posts for AA batteries lately, but these VARTA cells seem to remain the cheapest AA Alkaline batteries available at the moment (excluding the odd clearance line that pops up from now and then at coles etc).
This is equivalent to $1.20 for a pack of 4. (at least 80% cheaper than the equivalent Duracell)

*Also available AAA alkaline $8.99 for 24 pack.
Varta is great (after Altec Power) in my opinion. Have been using these several years and for general use I find this batteries could last as long (if not longer) as the branded batteries. Good deal!
