Amazon (AMZN - Get Report) Prime Day doesn't officially kick off until Tuesday, but the tech giant already has some early deals before the 30 hour blitzkrieg of sales begins tomorrow.  

Starting at 9 PM ET on Monday, Amazon began selling a whole slew of items at discounted prices. Prime Day runs through 3 AM ET on July 12. 

Most if not all the deals are limited to subscribers of Amazon's Prime service, which costs $99 a year and comes with perks like two-day shipping, among other things. But last-minute shoppers can sign up for a free trial to take advantage of the service for a limited time. 

One word to the wise: act fast. Amazon has multiple Lightning Deals, or discounts that are only available for a few hours and in limited quantities, so keep refreshing that page. 

While there are plenty of deals that have steep discounts on TVs and kitchen appliances, Prime Day also has its fair share of weird items. Last year, for example, a pressure cooker was the highest selling item in the U.S., while electric toothbrushes were a big seller in the U.K. In all, Prime Day is expected to bring in more than $2 billion in sales.

The full list of Prime Day deals can be viewed on Amazon's website, but in lieu of viewing all 8,000 deals, we broke down the best of Prime Day so far: 

1. Amazon's Fire and Echo devices


Unsurprisingly, Amazon has some deep discounts on its own range of gadgets. A 16GB Fire 8 HD tablet is almost 40% off, bringing it to $49.99, but only for another five and a half hours. The Echo Dot is on sale for $34.99, making it a 30% discount, while the larger Amazon Echo is going for $89.99, instead of its usual price of $179.99. The $229.99 Echo Show, Amazon's touch screen version of the digital voice assistant, didn't have any discounts, unfortunately. 

2. An Alexa-powered smart home lock 

If you've ever been too lazy to get up and lock your own door, the August Smart Lock is the perfect solution and is discounted at $159.99 from about $195. It can be voice-controlled and connected to your favorite smart home app (including Amazon's Alexa, Apple Inc.'s (AAPL - Get Report) HomeKit or Alphabet's (GOOGL - Get Report) Google Assistant) or it can be controlled from your phone. 

3. More than $200 off a 55-inch Smart TV

One of the Prime Day deals generating the most buzz is the Element 4K TV, which is on sale for $399.99 -- a 38% discount from its original price of $649.99. It has 4K picture and comes equipped with Fire TV, which lets you bring in nearly every streaming service under the sun (Netflix, Hulu, Prime Video, HBO, etc.). As with every other item on Prime Day, it's only available while supplies last, so move fast if you plan on snagging one. 

4. Discounts on the Fitbit Blaze

If you're still interested in buying a smart watch, Amazon has the deal for you. The Fitbit (FIT - Get Report) Blaze is $60 off at $198.95 and packs plenty of handy fitness tracking tools. It can track your steps and workouts and also comes with PurePulse technology that will continuously monitor your heart rate. 

5. A $400 blender is nearly half off 

The BlendTec Total Blender is 40% off, making it $400. It has a ton of custom features and is commercial-grade, meaning it's a heavy duty appliance. It still costs $400, so obviously this is meant for people who are in the market for a high-end blender. But with six preprogrammed blending cycles, it'll definitely do more than just make a smoothie.

At the time of publication, Action Alerts PLUS, which Cramer co-manages as a charitable trust, was long AAPL and GOOGL.
