Dick Smith - 4xAA Eneloop Batteries + charger half price @ $14.99
Only available today (thur 5 april) at this price with delivery setting you back $4.95 total.
AAA batteries a bit more expensive @ $21.99 (4 pack), but combining them on the same transaction saves you on shipping, so still a pretty good deal imo.
