Following on from the discounted AA and AAA rechargeable batteries posted by pennypincher98, Coles have further discounted their Energizer Maxi charger + 4 AA 2000 MmAh battery pack from $23.95 (Originally discounted from $29.95) to $11.25.
Not too sure how much stock there is out there, so keep an eye out next time you're at Coles. I managed to pick up the last pack from my local Coles in Eltham.
Oh yeah this was the charger I was talking about btw :)
