Walmart offers the Rayovac Alkaline AAA, AA, C, D, and 9V Battery 26-Pack for $7 plus $5 for shipping. That's $0.46/battery, tied with our mention from a week ago, and $36 under the lowest total price we could find for these batteries in this quantity when purchased separately elsewhere. The pack contains eight AA, eight AAA, four C, four D, two 9-volt batteries.
