Batteries
Batteries are essential for many items in our households, from toys to cleaning devices and remote controls. The trouble with Walmart batteries is that they cost a lot of money but have a rather short lifespan.
The retailer currently sells a four-pack of Energizer Ultimate AA Lithium Batteries for $6.94. It might be better to buy in bulk at Sam’s Club, where you’ll find an 18-pack of the batteries for $19.98.
