It’s the second day of Amazon Prime Day, and there’s a fresh batch of Lightning Deals alognside to discounts on tech, beauty and vacuums, exclusive to Prime members. Lightning Deals often offer some of the biggest savings during the sale, but they only last for a few hours and rotate throughout the day. If you spot a Lightning Deal you’re interested in, add it to your cart and check out quickly before it expires.

As a contributing writer for NBC Select, I regularly cover major shopping events like Prime Day, Black Friday and Cyber Monday, so I know how to identify deals that are actually worth shopping. Below, I rounded up the best Lightning Deals available during Amazon Prime Day. I’ll continue updating this list throughout the sale as new deals go live.

Why are Prime Day Lightning Deals worth it?

Prime members can historically find some of the lowest prices of the year on products across categories during Amazon Prime Day, and Lightning Deals tend to offer the deepest discounts on popular products. Lightning Deals give you a short window to buy limited quantities of specific products, and the program only runs through June 26. Once Lightning Deals sell out, they’re gone for good.

All of my recommendations above are based on NBC Select’s previous coverage and reporting. I evaluated the quality of these Lightning Deals by running them through price trackers like CamelCamelCamel, and I only included those that:

• Are at their lowest price in at least three months
• Are 20% off or more
• Are highly rated with at least a 4-star average rating from hundreds of customers on Amazon
