ZDNET only writes about the deals we want to buy — the tools and products we want, need, or recommend. Our experts used established price comparison tools and trackers to determine whether a deal is actually on sale and how often it drops, looking for deals that were at least 20% off (or rarely were on sale).
We also looked at customer reviews to find out what it’s like from real people who already own and use the deals we’re recommending. Our recommendations may be based on our own testing in addition to extensive research and comparison shopping. The goal is to give you the most accurate advice to help you shop better.
