Walmart's big sale, designed to compete against Amazon Prime Day, is now live, with savings on all kinds of items, ranging from video games and school supplies to earbuds and smartwatches.

Amazon Prime Day officially got underway Tuesday, with the summer sales event slated to last through July 11. Competitors Target and Walmart are also holding multi-day sales events.

For example, the latest MacBook Air M4 is currently going for $849 at Best Buy right now, which is the same price as Amazon's sale. I'd personally rate this deal higher than Amazon's, too, since you can trade in at Best Buy for an additional discount of up to $550.

The Sonos Ace headphones are great for Sonos enthusiasts and newcomers alike. Right now, you can save $150 on a pair.
