Batteries for a pound

This is Brainstorm...one of the many Ben 10 characters so beloved by the wee man. After going on and on about needing batteries for his Omnitrix I finally agreed to make my first trip to the Pound Shop. Got a whole sheet of cells along with all manner of stuff and before I knew where I was had an armful of crap. I'm blaming tiredness but I then went to the counter and said 'How much are the batteries?' before remembering where I was. Donut
