Our top pick

The Amazon Fire HD 10 tablet is back on sale as of Sept. 9 for $89.99. That's 36% in savings, which isn't as jaw-dropping as the record-low $74.99 from Prime Day, but it still a great deal. If you're looking for a no frills tablet to browse social media, watch your favorite shows, answer a few emails, and do other daily tasks, the Fire HD 10 will suit you just fine. It's "lighter and faster than its predecessors, with a long battery life and vivid picture that makes it great for on-the-go entertainment," Mashable reviewer SaVanna Shoemaker wrote in her review of the tablet.

Rumors are swirling about a potential Apple Watch Ultra 3 drop or a new iteration of the Ultra 2. Either way, Amazon has taken the opportunity to discount the current Apple Watch Ultra 2 model with GPS and cellular connectivity to a new record-low $689. That's a savings of $110. The Ultra 2 sports a titanium case that's more durable and slightly larger than the Series 9. It also features built-in LTE, a programmable action button, a depth gauge, a water temperature sensor, an emergency siren, and double the battery power of the Series 9. At the time of writing, only the blue and orange ocean bands are still available at this price.

As of Sept. 9, the Dyson Pure Cool is back down to its record-low $349.99. That's 36% in savings. It offers air purifying along with cooling or purifying on its own, so it can be used year round. A built-in sensor automatically reports pollution in real time and senses and reacts to changes in air quality, removing 99.97 percent of particles as small as 0.3 microns. We haven't had the chance to test out this exact model, but we tested the similar Pure Cool TP04 and found that "the effortless experience and peace of mind justify the cost."

At just $64.99, the fourth-generation Amazon Echo is just $10 shy of the lowest price we've seen this year. A sleek, simple little speaker that responds to your voice commands, the Echo is one of the best ways to introduce Alexa's smart home capabilities into your household. It delivers premium Dolby sound whether you're jamming to playlists or just asking about the weather. Plus, you can connect other smart gadgets to it and control them all using the Echo as a central hub. While it's older than the similarly simple yet powerful Echo Dot, the fourth generation Echo is larger and has better sound quality overall.

Need a vacuum upgrade? The Shark Cordless Pro is down to its lowest price ever — just $219.99 at Amazon. It features a 0.25 gallon bin size, up to 60 minutes of runtime, a flexible silicone Powerfins Nozzle that digs deep into carpets, and the ability to convert to a cordless hand vac for more flexible cleaning. The only downside is that delivery might take a bit longer than Prime usually does, but it's still worth the wait for 37% in savings.
