Updated live: Not all Prime Day deals are good — we found 37+ that actually are

Prime Big Deal Days is here, offering discounts on tech, beauty products, kitchen gadgets and more during the 48-hour sale, which is exclusive to Prime members. I’ve covered Prime Day, Black Friday and Cyber Monday for five years as a reporter for NBC Select, so I know how to find deals that are actually worth buying. I combed through Amazon’s many deal pages — through thousands of discounted products —  to find the best October Prime Day deals. Each one I recommend below is highly rated, at least 20% off and at its lowest price in at least three months. I’ll frequently update this list throughout Prime Big Deal Days.
