Noticed these a week or two ago, £1.50 for a twin pack, substantially cheaper than when I needed to buy some!! CR123a lithium batteries x2. Ideal for some camera's but I use them in the wireless pir's on the home alarm. Showing as £3 clearance on asda direct but half that price in-store. Plenty left in Ashton-under-Lyne a couple of days ago, none in Chadderton. Hope this is of some use to some of you.
