Some products we'd recommend (that are already discounted on Amazon) include the Samsung UE55KS9000 4K TV, and the impressive Beyerdynamic T1 Generation 2 headphones for £750.

Amazon is, of course, pushing its own products too - so you can get its Fire TV stick, the Fire TV box, and the Echo and Echo Dot wireless speakers for less.

The offer is only available today (20th January) so get that saving while you can.
