If there's one crucial lesson to learn, it's this: Giant Amazon sales are the perfect opportunity to stock up on hyper-practical, everyday essentials. While it's tempting to focus on big-ticket items with drool-worthy deals, don't let those larger purchases distract you from the substantial savings available on smaller, indispensable things. Think batteries, power banks, or a portable car battery jumper. Batteries are exactly what you always need the moment you can't find them. No more pilfering from the TV remote to power your child's new toy. You, my friend, can become battery-rich—especially when you snag them at a discount during Amazon's Big Spring Sale, which is their biggest deals event since Prime Day.
