Best Prime Day under $25 deals 2025 More Prime Day deals under $25 When is October Prime Day 2025? October Prime Day runs on Tuesday, Oct. 7, through Wednesday, Oct. 8. Are deals really cheaper on Prime Day? The legitimacy of Prime Day is a topic of heated debate every year. Primarily, Prime Day offers some legitimate deals, typically on flagship Amazon products such as Fire TVs, Echo devices, Kindles, and more. However, the best way to ensure you're getting an actually deal is to prepare to shop for offers and use price tracking tools to make sure you don't fall victim to brands marking up items to "discount" them later. Luckily, these offers are all under $25, so they won't break the bank -- even if they do end up being an impulse purchase or a sweet treat (I'm not judging). 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.
