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.

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 like Walmart, Best Buy, and Home Depot have Prime Day competition sales that are especially useful if you don’t have Amazon Prime.

• Walmart’s Prime Day competition sale begins at midnight on July 8 and will include deals up to 50% off. It’s an especially good option if you have Walmart+. 

• Best Buy’s Prime Day competition sale, “Black Friday in July,” runs through Sunday, July 13 and has some of the best tech sales online. It’s an especially good option if you’re a My Best Buy “Plus” or “Total” member.

• Home Depot extended its 4th of July sale through at least July 9, competing with some amazing deals of its own. It’s an especially good option if you’re looking for power tools, appliances, or outdoor equipment.
