FAQs

When is October Prime Day? 

Amazon holds a Prime Big Deal Days sales event every October. This year, October Prime Day is happening on Oct. 6 and 7.

How did we choose these Amazon Prime Day deals?

At ZDNET, we write about legitimately good deals on products we’ve tested, covered, and would recommend. As a consumer electronics reviewer, I test dozens of products throughout the year. I also cover deals throughout the year, so I’ve become familiar with price fluctuations, which helps me determine which deals are actually worth your hard-earned money.
