Went in to get the Maplins to get their own brand Lithium batteries and noticed that the Energizer AA & AAAs were bogoff.
Marked up at £6.99, I got 6 packs and they scanned in at £6.59 each.
These are supposed to be the best for digital cameras and came supplied with my camera.
Offer is on until xmas so just depends on their stock level.
The next cheapest was 7dapshop at approx 6p more per battery plus you'd have to rely on Royal Mail !!
But you can just walk into Maplins and pick these up :-)
