Amazon Kindle Paperwhite is $30 off right now on Amazon Prime Day Eve

There's been a significant Amazon Kindle Paperwhite price drop today, just hours before the Amazon Prime Day deals kick off for a 30-hour stretch.

Amazon Kindle Paperwhite is $30 off today only, which means you're paying $79.99 for the most popular Amazon e-reader, as opposed to the usual $109.99.

Bear in mind that this is a Certified Refurbished Kindle Paperwhite e-reader, according to Amazon, which means it's likely an open box scenario in which someone bought it and returned it within 30 days, not wanting it.

This is the best-selling Kindle, but you won't be able to see today's deal unless you're a Prime member in the US or Prime Student subscriber.

More Amazon Prime Day news to come

Amazon Prime Day is now shaping up to be a massive sales day for the online retailer, on the scale of its Black Friday and Cyber Monday deals.

Almost every Amazon device seems to be on sale, including Amazon Echo, and we expect the company to be hawking more of its goods.

Amazon Prime Day is technically tomorrow, starting at 6PM ET / 9PM PT, dipping into July 10. The official 'Prime Day' date is all day on July 11.

With deep discounts like this one for the Kindle Paperwhite 3rd Generation, we expect to see more refurbished items with price drops percentages in the double digits.

It's a good sign. We'll have more early deals, leaks and a rundown of the discounts at the link below.
