As someone who shops on Amazon for a living, I've seen my fair share of flashy "deals" that don't actually deliver. But when it comes to Prime Big Deal Days, which is happening October 7 through October 8 this year, the markdowns are the real deal. And this year, those epic discounts are rolling in early! We're talking up to 80% off across fashion, beauty, home, tech and even travel essentials, so you can snag luxe-looking finds and everyday upgrades for way less.
