New to Prime Day? We have a primer on everything you need to know. Sales are accurate at the time of publication, but prices and inventory are always subject to change. 

The other day, I pointed readers to this Ring Floodlight Cam on sale for $100, and today I wanted to highlight a less-expensive option: This Blink video doorbell. It can be yours for $29.99, a steep drop from the list price of $69.99. But only if you act fast: Prime Day is nearly over.

While the Blink cam doesn't have the bells-and-whistles of more expensive options, if you want a reliable, no-hassle video doorbell, and you don't want to pay more than it costs to eat lunch, you can get it on Prime Day.

Instead of being hard-wired, the Blink camera comes with three Energizer lithium batteries and a Blink Sync Module that will keep your doorbell working for up to two years, so the set-up is a five-minute snap, after which you'll have a door camera that detects motion and automatically records, even in the dark—it has night vision. You can also talk to whoever shows up through the Blink app, and if you connect it with an Alexa device like the Show 5, you can get a live view of your Uber driver on a separate screen.

Looking for something else? Retailers Walmart and Best Buy have Prime Day competition sales that rn through July 13 and are especially useful if you don’t have Amazon Prime.
