If you need batteries, here's a nice deal for you! Right now, you can head over to ToysRUs.com where they are offering a free package of Toys 'R' Us Ultra Alkaline batteries when you purchase another at equal or greater value. The 20 count packs of batteries are priced at $6.99, so that makes each package just $3.50, which works out to just $0.17 per battery.
To get this deal, simply add two packs of the batteries that indicate they are a part of the buy one, get one free promotion (they can even be different types of batteries) to your cart and one will automatically show as free. This deal is limited to one free package of batteries per order. Then you can choose in-store pickup to avoid shipping costs and pick them up the next time you're at your local Toys 'R' Us store.
If you aren't automatically directed to the battery section when you head to ToysRUs.com, simply search "battery" in the search box when prompted.
