Though Prime Day is a great time to get a solid discount on a big-ticket item, such as a pair of noise-cancelling headphones or a brand-new laptop (just in time for back-to-school), some of the best deals are actually the least expensive.For less than $25, you can find bargains on everyday essentials that you never seem to have on hand when you need them most. Things like a smooth-writing pen, rechargeable batteries (for when the remote inevitably dies in the middle of a show), or a charging cable when your phone is at 1%.It’s also a great time to stock up on consumable household items that you know you’ll use in the next few months, such as sunscreen, fragrance-free laundry detergent, or dishwasher pods. (Just remember that many of these things actually do have expiration dates, so don’t go overboard.)Here are the best products on sale for Prime Day under $25 — all of which have been tested by our journalists to confirm they’re best-in-class, with the prices vetted by the Wirecutter Deals team to verify they’re really worth buying now.
