Some of our favorite gadgets, home goods, tools, and more are deeply discounted during Amazon's annual Prime Day sale.

Amazon is hosting its longest-running Prime Day sales event this year, while other retailers have responded with competing sales.

Amazon Prime Day deals are here for four days this year, but that doesn’t mean all your favorite products will be on sale for that full length of time. Popular products tend to sell out quickly when the discounts are this deep, so if you’ve had your eye on something, you don’t want to miss your chance to grab it on sale.
