Look; I think it makes more sense to buy good rechargeable batteries than to keep shelling out for disposables, in general. I do. It’s better for the environment; it’s better for your pocketbook.
That said, I will often give my kids “regular” batteries so that I don’t have to worry about whether or not those batteries (and the toy they’re in) end up getting lost or damaged. And sometimes the batteries aren’t charged and we have a Wii emergency. Or something. So when I saw that today’s Graveyard Mall Deal of the Day is 100 alkaline AAA batteries for about $15 shipped, I couldn’t help thinking that that would keep us in batteries for a long, long time.
