Here are 9 Prime Day deals that are 50% off that I'm buying as a shopping expert

My top pick for the best cheap Prime Day deal is the best-selling Kasa Smart Light Bulb, available for just $6.99, making it a must-buy. The dimmable light bulb can be controlled remotely via the Kasa app, and it is compatible with Amazon Alexa and Google Assistant, allowing you to use your voice to control your lights.

Okay, this is only 48% off, but it's so cheap and handy that I had to include it in the list. You can add smart capabilities to any device in your home with the best-selling Amazon Smart Plug on sale for just $12.99. With over 500,000 positive reviews on Amazon, the smart plug works seamlessly with Amazon Alexa, allowing you to control lights and appliances with just your voice.

I've had my eye on the Blink Mini 2 since its release, and now that it's on sale for just $19.99 - it's a must-buy. The compact security camera features two-way audio and will alert your phone when motion is detected. The Blink 2 also includes a 1080p HD live view, night view in color with a built-in spotlight, and a wider field of view.

Get a cheap streaming device with Amazon's standard Fire TV Stick on sale for just $17.99 with code FTVHDADD at checkout. In our Fire TV Stick review, we found that the original version offered a cost-effective way to add essential smart features to your TV, including access to HD streaming apps, Alexa voice controls, and the ability to control other smart home devices.

The best-selling Fire TV Stick 4K streams shows and movies on your TV in ultra-high-definition 4K resolution and is also on sale for just $24.99, thanks to Amazon's 50% discount. It's a solid streaming stick with access to all the major apps and support for voice controls through Alexa.

This is only 44% off, but it's my favorite Amazon gadget and it's on sale for a record-low price. Amazon's brand-new Echo Spot pairs a 2.83-inch touch screen with a 1.73-inch front-firing speaker, making it an ideal smart alarm clock. With Alexa onboard, you can ask the assistant for the weather, play music, or even schedule alarms.

This might be one of the best Prime Day deals: Amazon's latest tablet, the Fire HD 10, is down to a new record-low price, and I don't imagine it will drop further on Prime Day itself. It features a large, bright 10-inch Full HD display, 3GB of RAM, and an octa-core processor for enhanced performance. The tablet also works with Amazon Alexa and provides an impressive 12 hours of battery life.

I already own the best-selling Ring Video Doorbell and can't imagine living without it. The smart doorbell includes a built-in battery and allows you to see, hear, and speak to anyone from your phone or computer. Today's Prime Day deal from Amazon is a record-low price.

The 4th generation Blink outdoor security camera features enhanced motion detection, two-way audio, a two-year battery life, and works with Amazon Alexa for hands-free control. Today's Prime Day deal is a massive 62% discount and a record-low price.
