Energizer currently is running a promotion with $10 iTunes cards. At Sam's Club, a 40-pack of AA batteries is $14.88, but it comes with enough codes to get a $10 card. Good deal for those in need of batteries and who also have an iPhone or iPad!
Are they standard alkaline or the lithium type? The only kind of disposable AAs I use anymore are the lithium ones because they are significantly lighter than standard alkaline or NiMH chemistries (and therefore are good for use in mice), and they also perform a lot better in extreme cold weather (so good for flashlights for outdoor use in the winter, etc).
