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.

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

As Prime Day winds down, you can still get big deals on big screens from Hisense, LG, Samsung, and others, but you need to act fast!
