All-new Kindle - £49.99

Meet the all-new Kindle, now with a built-in adjustable front light so you can read indoors, outdoors and at more times of day. Purpose-built for reading, Kindle features a glare-free touchscreen display that reads like printed paper, even in direct sunlight... Buy here.

I tend to look at things like Amazon Prime Day with a skeptical eye, but under £50 for the new Kindle is great value. Love mine to bits.
