Amazon is dramatically discounting two of its top eBook readers for Amazon Prime Day.

Starting at 6pm BST today, Monday 10 July, Prime members can snag an Amazon Kindle Paperwhite or Kindle Voyage reader at £79.99 and £129.99 respectively. Amazon Prime Day 2017 runs until the end of play tomorrow, Tuesday 11 July.

All versions of the Paperwhite and Voyage are discounted, so you can also buy the white Kindle Paperwhite, plus versions of both devices with 3G connectivity as well as the standard Wi-Fi.

You can also choose to have "special offers" - Amazon suggestions on your device - switched on or off. The latter costs a bit more.

The Amazon Kindle Paperwhite device has a 6-inch screen with 300ppi E Ink resolution. It also has a built-in backlight light to improve reading conditions in all light, whether it is day or night.

The Amazon Kindle Voyage also has a 6-inch screen with 300ppi resolution. It includes an adaptive front light, which changes brightness depending on ambient lighting conditions, which works with the backlight to further improve reading. It is also lighter than the Paperwhite, weighing 180g in preference to 205g.

Both devices have touchscreen displays, but the Voyage adds "PagePress" touch in the side bezels.

Amazon Prime membership is required to buy bargains on Prime Day. It usually costs £79 a year or £7.99 a month. You can also sign up for a 30-day free trial if you've not been a member before and cancel at any time within the free period.
