We only choose products that meet our high standard of coverage, and that we've either used ourselves or researched carefully. We compared the prices against other retailers like Best Buy and Lowe's and only included the deals that are the same or better (not including promotional discounts that come from using certain credit cards). All deals are at least 20% off, with the occasional exception for products that are rarely discounted or provide an outsized value. Read more about how the Insider Reviews team vets deals here.
