We thoroughly investigated and checked price histories on these products across retailers for the past six months. Any deals under 15 percent off we automatically filtered out, and any products that have been purposefully price-gouged to appear like a deal we did not include. Every product on this deals list has been verified that it is one of the lowest, if not the lowest, deal in the past six months.
Additionally, we checked the products themselves, combing through reviews across multiple sites to make sure the products on sale are ones that we can stand by as a ZDNet Recommends product. If a product has been reviewed by one of our contributors, we make sure to link it so you can see what our top tech experts have to say about it.
