If we can teach you anything, let it be this: Giant Amazon sales are the time to stock up on hyper-practical, everyday things. Of course, you should take advantage of drool-worthy deals on big-ticket items. But don’t let larger purchases distract you from the savings you could score on the smaller things. Like batteries. Or power banks. Or a portable car battery jumper.
What can we say? Batteries are the exact thing you always need the moment you can’t find them. No more stealing from the TV remote to run your kid’s new toy. You, my friend, shall be battery-rich — especially after getting them discounted as part of Amazon’s Big Spring Sale (it’s biggest deals event since Prime Day, by the way).
