Just picked these up in store today
Stand states AAA, AA, C and D and I think the 9V were in offer
Any two packs for £3 or even better 4 packs for £5
I got 2 packs of AAA and AA 4 in each pack
Should have been £2.89 each total £11.56 according to my receipt but saved £6.56
Great time to stock up for Xmas
Link is to web store but not on offer there just to show you price and type
Not sure how long offer for will update next time I go in there unless someone else knows?
