And right now, the Fire TV Stick is on sale for $25 at Amazon, which is a real bargain compared to its normal $40 price.

Shoppers can get 33% off the Fire TV Stick 4K Max — Amazon's most powerful streaming stick yet — bringing the device down to its record-low price of $40. With the most advanced model in Amazon's Fire TV Stick lineup, you can enjoy smoother 4K streaming of over 1 million movies and TV episodes.

The deal is based on the standard Fire TV Stick which usually costs £44.99. That has been dropped to just £24.99 for a limited time but then there's a further 20% reduction if you give Amazon your ageing device. That means you'll pay less than £20 for this upgrade plus Amazon will also throw in a gift card as well.
