Over the past few days, Amazon has begun slashing the price of its own gadgets as part of a wider Mother's Day sale. Yesterday, we saw the Echo Show 8 and Echo Show 15 fall back to all-time lows, and today it's the turn of the retailer's popular Kindle e-readers, which are now offering savings of up to 41 percent.

Leading the way is the Kindle Paperwhite, which is typically priced at $140, but has fallen back to an all-time low of $105 in this particular sale. The standard Kindle is also down to $55, just $5 off its lowest ever price.

The fifth-gen Paperwhite, which was refreshed for the first time in three years this past September, has a larger screen than the previous model at 6.8 inches (compared to the six-inch display on its predecessor). Amazon says the 300 ppi screen looks like real paper and its glare-free screen enables "easy reading" in all conditions, even direct sunlight. Not only is it compact, but it has a waterproof design that will ensure it remains operational when splashed. There's also support for USB-C fast charging.

If you're looking for something a bit more premium, the Kindle Oasis is on sale too. The 8GB model, which typically costs $250, is currently available for $200. The e-reader has previously been as low as $175, so it's not currently near its all-time low, but still offers $50 off its usual price. The Oasis features a 300 ppi display, though the screen is slightly larger than the Paperwhite at seven inches. It has physical page turn buttons, an IPX8 waterproof rating and a color-adjustable front light.

It may also be a good time to encourage your child's love of reading. Amazon is selling the Kindle Paperwhite Kids for $120, or a full $40 below the usual price. The standard Kindle Kids is also on sale for today at $65 with a decent $45 (or 41 percent) discount. They both come with a two-year "worry-free guarantee," a protective cover and a 12-month Kids+ subscription with access to thousands of books.
