When Prime Day launched back in 2015, it was a 24-hour sale to celebrate Amazon’s 20th anniversary. Over the past decade, it has evolved — or devolved, in the eyes of many — into a multiday, multipronged online-shopping juggernaut. But even the veteran deal hunters here at Wirecutter were stunned to learn that this year Amazon had extended the event from two days to four.But double the days doesn’t mean double the deals.If there’s anything we’ve learned from covering Amazon Prime Day for the past 11 years, it’s that most of the discounts you see aren’t worth your while. And although we go the extra mile to curate the best deals during big sales events like this, we also go to great lengths every day to make sure that you’re spending your hard-earned cash on things that will last.It starts with our independent reporting and rigorous testing. You can rest assured that every product you see here is something that our journalists have tested, reviewed, and deemed one of the best in its category.On top of that, the Wirecutter Deals team tracks prices all year round to confirm that every discount we feature is actually a good deal. That means we can even tell you about the quality of the deal, such as if it’s the lowest price we’ve seen this year (or ever).In reviewing thousands of Prime Day deals, we find only a small fraction that meet our exacting standards. We’ve rounded them up here, because there’s no need to get swept up in the hype, but we do want you to delight in finding just the right thing — whether it’s a big-ticket electronic item, a restock of your favorite skin-care or wardrobe basics, or a gift for someone special — at the best price possible.Note that an Amazon Prime account may be required to secure the deal prices you see below.
