Best Buy has the 48 ct packs of Insignia AA or AAA Batteries for just $9.49 (reg. $17.99). Hurry, this price is good for today only (7/8).
I love deals on batteries because we go through a ton and I hate going to get new batteries and finding out we have run out of them!
I would recommend buying several packages and get free shipping when you spend $35 or more. I have checked though, and these are currently are available for store pickup at all of the Utah stores.
