What makes a "good" Prime Day deal can get pretty subjective. Are we going off of the recency of an item's release? Its position on the scale of niche to universally usable? The frequency that an item goes on sale at all? Probably a mix of all three. One foolproof way to find the best Prime Day deals is to look at pricing history: If an item has never been cheaper than it is right now, that's inarguably a good Prime Day deal.

With the help of trusty Amazon price tracker camelcamelcamel, we're vetting the best Prime Day deals from big brands like Apple, Sony, Oura, and Amazon itself to bring you a list of the most popular products that are actually at record-low prices. Some are prices we've only ever seen during Black Friday, some beat what we saw during Black Friday — all are at risk of disappearing before the end of Prime Day on June 26.

Fun fact: 2026 is the first Prime Day season that we have a Walmart version of camelcamelcamel. Use camelmart to compare Walmart price history during its Summer Deals event, live now through June 28.

Oura Ring 4

Read Mashable's full review of the Oura Ring 4.

The new Oura Ring 5 was released just in time for Prime Day, but it's not on sale. Instead, we want to direct your attention to our reigning pick for the best smart ring: The Oura Ring 4. The silver version has dropped to a new record-low price of $214 at Amazon, down more than $130 from its original $349. That's followed by three other colors on sale for $226 and the gold option on sale for $259. Prime members can order the Oura Ring sizing kit for just $8.49.

The Oura Ring 4 is super slim and comfortable, and doesn't look much different than any other minimalist band that you could add to your lineup. For such a small tracker, the Oura Ring draws quite a comprehensive picture of your health. It tracks daily metrics like steps and sleep, plus longer-term analysis of stress levels, chronotype, and cardiovascular health.

Lego Imperial Star Destroyer

One of the most exciting Prime Day Lego deals is the Lego Star Wars Imperial Star Destroyer set. The hype is partially related to the rarity of this price drop — we've only seen it once before, during Black Friday and Cyber Monday 2025 — and partially related to the rarity of an included mini-figure. Cal Kestis is one of the seven mini-figs included in this set, and as of June 2026, isn't available in any other sets. He is going for between $40 and $60 by himself on eBay, if that tells you anything.

Sony WH-1000XM5

Read Mashable's full review of the Sony WH-1000XM5 headphones.

If you've been trying to decide between the Sony WH-1000XM5 and WH-1000XM6, think of it this way: This Prime Day, buying two pairs of Sony WH-1000XM5 headphones for $198 each would barely cost more than a single pair of WH-1000XM6 headphones (on sale for $378). That's how low this new record low is — a full 50 percent off from the 1000XM5's original $399.99.

Though the WH-1000XM5s are a few years old at this point, they're still a really solid (and really attractive) pair of noise-canceling headphones. You'll get a ton of premium equalizer settings and great sound quality overall, plus up to 30 hours of battery life.

Dyson Supersonic Nural

No need to find a Dyson Supersonic dupe when the most advanced Dyson hair dryer itself has fallen to a new record-low price. At $329.99, you can score the Dyson Supersonic Nural (in Amber Silk) for just $10 more than the regular Dyson Supersonic's sale price.

The Supersonic Nural comes with a carrying case and four attachments: a wave and curl diffuser, flyaway attachment, wide-tooth comb, gentle air attachment, and styling concentrator. Compared to the regular Supersonic, the Nural features smart upgrades like automatic temperature lowering near the scalp, automatic airflow pause when set down on the counter, and attachment learning. The Nural will remember the air and temperature settings that you like to use and adjust accordingly when you swap attachments.

Kindle Paperwhite

Read Mashable's full review of the 2024 Kindle Paperwhite.

Our resident e-reading expert and recent BookCon attendee Samantha Mangino has tested a thick stack of e-readers, from Amazon's top models to Kindle alternatives from Kobo and DuRoBo. She wouldn't hesitate to recommend the 2024 Kindle Paperwhite over the others, even at full price — so it's just the cherry on top that this beloved Kindle is $35 cheaper today. We saw this record-low price during Black Friday, but not during Amazon's Big Spring Sale in March.

This Kindle deal pairs nicely with Amazon's Prime Day Kindle Unlimited offer: three months for free.

Ninja Slushi

Read Mashable's full review of the Ninja Slushi.

The $100 Prime Day discount on the original Ninja Slushi is so good that it sold out at Amazon before the second day of Prime Day. However, we can still use the listing to see that $199.99 is the lowest price on this 88-ounce Slushi model

Luckily, you can still find the Slushi for $199.99 at retailers like Target, Best Buy, and the SharkNinja website (this is where the most color options are, like the Soft Sage option pictured above). Not a bad price to pay for on-demand frozen drinks on an otherwise hot, boring summer day — no ice needed. Senior shopping reporter Leah Stodart uses hers for fun cocktails and protein shakes alike, and notes that it takes up much less counter space than the new Ninja Slushi Twist.

Apple Watch Series 11

Read Mashable's full review of the Apple Watch Series 11.

We don't always recommend upgrading to the newest version of an Apple product just because it's the newest version. But the Apple Watch Series 11 has enough upgrades that we genuinely think it's worth it, especially now that the 42 mm model has dropped well below $300.

Mashable's Stan Schroeder was so impressed with the Series 11 experience that his review is "perhaps the easiest review he's ever had." The big deal here is the battery life: The Apple Watch Series 11 can easily last for a day and a half on one charge, beating the moody battery life of the Series 10 by several hours. Plus, there's a new Sleep Score feature.

Dreame X60 Max Ultra Complete

Read Mashable's full review of the Dreame X60 Max Ultra Complete.

Up until June 23, the Dreame X60 Max Ultra Complete had been sitting at an early Prime Day price of $1,459.99 (already a record-low price in itself). No one would have been surprised if that was the cheapest this Dreame model would go this summer. But for the official start of Prime Day, $115 more dollars have been shaved off of the best robot vacuum mop combo of 2026.

Really, the biggest downside of the X60 Max Ultra Complete had been its steep $1,699.99 MSRP — resident robot vacuum expert Leah Stodart quite literally said that it "sucks that it's so expensive" in the headline of her review. $1,344.99 is much more in line with the expected premium price tag of other flagship robot vacuums. If you're picky about cleaning, this is the most thorough robot vacuum for carpet cleaning and corner mopping that you'll find.

Microsoft Surface Laptop 7

Read Mashable's full review of the Microsoft Surface Laptop 7.

The biggest Microsoft Surface news of June had to do with the new Surface Laptop 8 announced on June 16. But during Prime Day, it's hard to concentrate on anything other than the Surface Laptop 7's new record-low price: It's now just $1,229.99 after a shocking 44 percent price drop.

In the midst of RAMaggedon, this premium Windows laptop deal is a steal to a whole new degree. This exact same Surface 7 model sold out at Best Buy when it was on sale for $1,699.99, so you'll want to move faster than the Snapdragon X Elite chip to snag this before it's gone.

The Surface Laptop 7 has been beloved by Mashable since its release in 2024. Senior Shopping Reporter Haley Henschel says, "While its CPU isn't the freshest anymore, it still impresses as a whole: It features a 23-hour battery life, a microSDXC card slot, and a 2.5K touchscreen that's brighter and smoother than a 15-inch MacBook Air's screen."
