(Image credit: Amazon / Edited by Gemini) Want to refresh your smart home? Now's the time to do so, as Amazon is offering limited-time deals on Ring, Blink, Fire TV and more . These are some of the best deals I've seen so far this year. Some of my top picks include the Fire TV Stick Select on sale for £29 , perfect to give your TV an upgrade and stream all your favourite shows in 4K. In addition, the Kindle Kids is on sale for £89 .

I've listed all the best Amazon device deals below!…
