Amazon’s 2018 update to the Paperwhite turned it into the best Kindle for most people, and today only, the company is offering $40 off the new, waterproof model, marking the lowest price we’ve seen on it yet.

There have been other sales on the new Paperwhite before, but today’s deal — which starts at $89.99 for the cheapest, 8GB model with Wi-Fi and Amazon’s advertisements — is the cheapest yet. All the models of the new Paperwhite are on sale, although options like the , cellular connectivity, and removing Amazon’s “Special Offers” ads will obviously bump that price up.

But no matter which model you’re interested, it’s hard to turn down a straight $40 off the usual price tag, especially if you’ve been looking to use your Kindle in a bath or by the beach. The discounted price is only available for today, so you’ll want to snag one while the discount is still good.
