I got some Christmas presents that requires batteries, like single A, AA, and AAA. Where do I buy these batteries?
Pretty much any dollar store.
Gas stations, drug stores, grocery stores, hardware stores, hobby stores, darn near any kind of store sells them. Have your mom take you since you are not old enough to know this.
You won’t find them at a liquor stor. Other than that you should be able to find quite easily.
amazon, target, walmart, best buy, home depot, office max, jewel osco, meijer, newegg, gamestop. maybe local gas stations.
