Query: I would just say BUY RECHARGEABLE BATTERIES!

Why pay $9 for a bulk pack of throw-away batteries when you can just buy a 4-pack of rechargeables for a few bucks more? A one-time payment of batteries you can charge 1000 times will break even on the long run if you project prolonged use of devices taking AAs. Also, every charge cycle of rechargeables lasts longer than the total mAh of throw-aways.
