Toys "R" Us still cuts up to 30% off select packs of its Toys "R" Us alkaline batteries. Even better, buy one pack and get a second pack of equal or lesser value for free. With prices starting at $4.99, that's tied with our mention from last week as the best discount we've seen on these items from Toys "R" Us. Opt for free in-store pickup to avoid the shipping charge, which starts at $5.56. Sales tax is added where applicable.
A best bet is to buy two Toys "R" Us AAA Ultra Alkaline Batteries 20-Packs (pictured) for $6.99. With free in-store pickup, that's $0.17 per battery and $11 under the lowest price we could find for this quantity of similar batteries elsewhere.
