Another Prime Day is here already. Amazon's Prime Big Deal Days event, sometimes called October Prime Day, continues today through tonight, and we're scouring the internet for the best savings so you don't have to. 

Whether you're looking to score on tablets, security cameras, kitchen appliances, random odds and ends, or are just bored and want to shop around for nothing in particular, I've rounded up some notable deals you can purchase today for under $100. 

In selecting these 60+ deals, I considered which products were worth your while, based on the customer reviews, the substantiality of the deal itself, and whether or not the product was something ZDNET has tested for itself. Below you'll find deals on security cameras, headphones and earbuds, and even some home stuff

FAQs

When is Amazon's October Prime Day 2024? 

Amazon's October Prime Day is on Oct. 8 and 9, though some products will be discounted a few days before and after the deals event. 

Are products really cheaper on Prime Day? 

The short answer is: it depends. The long answer is that brands decide at what price they'd like to discount their products at, based on demand and availability. Sometimes, they will inflate the price ahead of Prime Day to make discounts look more attractive than they actually are. But other times, you will see products discounted well below their original price. When we see a good or rare deal on a loved piece of tech, whether that's AirPods or a TV, we try to call it out through our Prime Day coverage. We'll also do our best to tell you whether something is worth your money based on our own experience with the product and customer reviews. 

How did we choose these October Prime Day deals?

ZDNET only writes about deals we want to buy -- devices and products we desire, need, or would recommend. Our experts looked for deals that were at least 20% off (or are hardly ever on sale), using established price comparison tools and trackers to determine whether the deal is actually on sale and how frequently it drops. 

We also looked over customer reviews to find out what matters to real people who already own and use the deals we're recommending. Our recommendations may also be based on our own testing -- in addition to extensive research and comparison shopping. The goal is to deliver the most accurate advice to help you shop smarter.
