Picked up few packs of AA 2300mAh batteries in my local Aldi today for £1.99 reduced from £2.91 i`m sure it said.
They also had packs of 4 AAA`s for same price but didn`t look at what the capacity of those were.
I`ve not tried them out yet as I`ve just got them but 4 AA 2300mAh batteries for £1.99 is certainly worth a punt.
Instore only ovbiously. They were on the racks next to each till point beside the other batteries
