This story is part of Amazon Prime Day 2021, CNET’s guide on everything you need to know and how to make sure you get the best deal.

Amazon Prime Day 2021 is coming early next week, and Walmart, Best Buy and Target have their own sales starting from Sunday. The result? There’s a number of excellent deals on streaming devices starting now.

All of the below devices are simple ways to upgrade older TVs with the latest streaming services, with some at or near all-time low prices. However, we would exercise caution on buying Amazon devices till Monday — for example, the Fire TV Stick 4K will match its lowest-ever price of $25, and there’s likely more where that came from.

In the meantime, there’s still a lot of great options including 40% off the TiVo 4K Stream and a $10 discount on the Roku Express 4K Plus

Note that prices and availability were accurate at the time of publication, but they may fluctuate.

The Fire TV Cube combines an Alexa voice-controlled speaker, a Fire TV 4K video streamer and a universal remote control in one device. If you like using your voice to control the TV — not to mention other devices in your Alexa-friendly household — it may well be worth taking the plunge on this interesting all-in-one product, marked down from $120 to $100. Note that this is the newest (2019) version, which has added some nice improvements since we first evaluated it in 2018.
