I just picked up 3 packs of 4+4 free packs on extra long life batteries at boots. The 4 packs currently have 4 free for £2.99. However they are also on 3 for 2. So a bargain price of only 5.98 for 24 batteries. Stock up for Christmas with all those new kids toys!!!!
Packs of AAA batteries were also on the same offer so you could mix some AA's with AAA's if you wanted.
I've checked on line and this offer doesn't exist. Also these were displayed at the ends of some aisles hanging up.
More details added from the Web.
Boots AA Extra Long Life Alkaline Batteries are specifically designed for use in products such as mp3 players, radios, digital cameras, torches, motorised games and toys, clocks and other devices that require this size of battery.
