Toys “R” Us again 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 month 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 $5.29. Sales tax is added where applicable.
