Walmart is competing with Amazon this Prime Day, offering great savings on our favorite laptops, 4K TVs, earbuds, and other WIRED favorites.

Milwaukee’s two-pack of high-output batteries is another great deal, currently an impressive 50 percent off—a savings of $150—at Walmart. These 18-volt batteries are compatible with over 150 M18 cordless tools and have a 6-amp-hour capacity. They also come with overload protection and a three-year warranty.

Walmart has launched its own summer sale event to counter Prime Day. Only some deals are actually worth grabbing.
