On a budget? These are the best deals under $25 ahead of Amazon Prime Day

When is Amazon Prime Day? 

This year, Amazon set its annual Prime Day event a little earlier, bumping it up into June instead of its usual July slot. The Prime Day sales event is officially from June 23-26, but you can expect sales prior to and even after the event. 

How did we choose these early Amazon 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.
