You’re in luck if you’ve pined for Amazon’s Kindle Oasis eReader but have been put off by the official $250-plus price. Amazon’s Woot brand is running a one-day sale on the previous-generation (that is, from 2017) Kindle Oasis with 8GB of storage and ads that drops the price to just $149.99. That’s as much as you’d normally pay for a brand new Kindle Paperwhite without ads, and might be worthwhile if you or a loved one is a digital bookworm. Be sure to act quickly — the deal expires at midnight.

The 7-inch, 300ppi display remains as crisp and easy to read as ever, with built-in lighting on hand to help you finish chapters in the dark. This was also the first water-resistant Kindle. It can last in freshwater for up to an hour at depths as great as 6.5 feet. You may not want to count on the Oasis surviving an accident at a saltwater beach, but it’s otherwise resilient.

The Kindle Oasis offers many other mainstays of many Amazon eReaders at this sale price. You’ll get weeks-long battery life, Audible audiobook support, and free LTE data to keep you connected when away from Wi-Fi.

The modern Kindle Paperwhite comes close in some respects. You’ll get a 300ppi screen, LED lighting, water-resistance, and cellular data. The older Oasis boasts a larger screen, though, and you may prefer its dedicated page turn buttons. Think of this as a slight upgrade that helps you read more comfortably without spending as much as $100 more for the privilege.
