There's up to 50% off Amazon devices – but should you buy now or wait for Black Friday?

The latest wireless Ring Doorbell has been discounted back to its lowest-ever price, so it's a great pickup ahead of Black Friday. We've tested more advanced versions and have been impressed with the video quality and night vision colour, but it's a shame that some of this device's value is usable exclusively with a Ring Protect subscription. However, if you're fine with paying for a subscription or already using a Ring-based home security system, it's worth the cost.

The newest version of Amazon's standard Fire TV Stick has been $2 cheaper than this before, but it remains an inexpensive way to add or upgrade the essential smart features in your TV, including access to streaming apps in HD, Alexa voice controls and the ability to control other smart home devices. This is a decent option if you're looking to upgrade your streaming setup on the cheap.

As the name suggests, the Fire TV Stick 4K streams shows and movies on your TV in ultra-high 4K resolution, with access to all the major apps and voice control support through Alexa. It's a good offer for a solid streaming stick that could be an upgrade to some slower and clunkier in-built TV services and apps. I wouldn't rush to get this deal, however, as it's been down to as low as $21.99 in previous sales. That was for an older version, but it should get closer to that when Black Friday is underway proper.

The newest version of Amazon's premium streaming device, the Fire TV Stick 4K Max, streams the same content in the same quality as the standard 4K version, but the extra power inside means you get faster performance when navigating apps and searching for shows. Plus, it uses WiFi 6E technology to give you a more stable and consistent streaming experience over the majority of built-in TV services and apps. This is the same offer we saw on Prime Day, but it was down to $32.99 during last year's Black Friday, so I'd wait until next month before picking it up.

Amazon's latest sale includes this 32-inch TV on sale for $109.99 – that's just $10 more than the record-low price. While the Amazon 2-Series TV is just a basic HD display, you get smart capabilities with the Fire TV experience and Amazon Alexa on board for hands-free control at a bargain price. It's far from the best TV in the world, but if you need something small and basic for the kitchen or a kid's room, then this is fine for the job.

The 50-inch Amazon Fire TV is the mid-sized version of the budget-friendly 4-Series range and it's now down to its lowest-ever price. It's a nice buy if you're on a budget, as the premium 4K resolution delivers excellent clarity and picture quality for TV shows, movies, sports and general viewing. All major streaming apps are ready to go, too, plus there's voice control support through Alexa. It's an all-around solid TV for the price that I'd buy if I needed an affordable and capable display.

Amazon's Fire TV Omni QLED Series is a big step up in the otherwise cheap and cheerful range of smart TVs. This set boasts premium features, including a QLED display for better brightness and contrast, HDR and Dolby Vision for brighter and more vivid colours, local array dimming for richer blacks and HDMI 2.1 support to deliver a top-quality picture for all-around viewing and fast response times for gaming. It's not always easy to find a TV of this size and with these high-end features for under $400, so it's an excellent buy for the budget-conscious without compromising on quality, but I'm confident it could be even less in the full Black Friday sale.

If you're looking for a slightly bigger smart home display, Amazon has the latest Echo Show 8 on sale for $99.99 – that's $20 more than the record-low price. The eight-inch display allows you to make calls, watch movies, check the weather, and control compatible smart home devices completely hands-free thanks to Alexa compatibility. The addition of room-filling spatial audio gives a big boost to all of these features to improve sound quality.
