Katie’s All-Time Favorite Amazon Finds Are on Sale For Prime Big Deal Days 2026

Including the viral TikTok gadget she can't cook without.

Graphic by KCM

Katie has built quite the following on TikTok — and, as it turns out, not just for the news. These days, she’s just as likely to show up in your feed with a clever product she genuinely loves. Think genius kitchen gadgets, easy everyday upgrades, and the occasional fashion find that makes you wonder how you ever lived without it.

Her recommendations tend to have one thing in common: They’re actually useful. They make life easier, save time, or, in the case of her beloved garlic peeler, spare you from an unnecessarily irritating task. And because Katie is candid about what earns a spot in her rotation — and what doesn’t — her picks have a habit of catching on.

So, yes, we went to Amazon. We know. But a good deal is a good deal, and we’re willing to make an exception. We rounded up Katie’s favorite finds in one place, from a barista-worthy milk frother to the everyday SPF she swears by. Many are marked down for Prime Big Deal Days 2026, which means if you’ve been waiting to buy that gadget you spotted in Katie's Obsessions, here’s your chance.

Katie's Obsessions on Amazon

Black+Decker Dust Buster

Amazon

$90 (22% off)

No one really enjoys chores, but a tool that makes them less annoying is worth talking about. Katie is a fan of this handheld vacuum for tackling everyday messes, from spilled flour to the dust bunnies that have the audacity to emerge from their hiding spots the second you’ve finished cleaning.

Katie's Book Club Pick: "Hollow Bones" by Jodi Picoult

Amazon

$34 (31% off)

If you haven't been following Katie's book club, it's time to hop on the bandwagon. This month, she's reading Jodi Picoult's newest novel, Hollow Bones. After losing her mother on 9/11, an emergency preparedness expert who has built her life around planning for the worst is forced to reckon with the limits of control when an unexpected crisis shakes her marriage and everything she thought she knew.

Nespresso Aeroccino Milk Frother

Amazon

$99 (50% off)

Making coffee at home is a habit that's better for your wallet and the environment — and having a milk frother makes a homemade brew much more enticing. Bonus tip: Katie adds cinnamon to her milk for a delicious (and sugar-free) treat in the morning.

$50 at Amazon

Salt and Stone Body Wash

Amazon

$36 (20% off)

While Katie usually avoids fragrances to prevent irritation, this scented body wash from Salt & Stone is an exception. "I love how fragrant it is, and it does seem to make my skin feel softer," she says. It's infused with hyaluronic acid and seaweed extracts, both of which help skin retain moisture, as well as vitamin C and niacinamide to help smooth texture.

Aerotrunk Compression Packing Cubes

Amazon

$24 (35% off)

Katie and John are constantly on the go, so they know a thing or two about packing efficiently. One of Katie's recent travel suggestions is to use packing cubes, which help organize your suitcase into tidy compartments. This set compresses down, so all you overpackers can rest easy and bring whatever you want on your next trip.

Dyson Airwrap

Amazon

$710 (30% off)

Listen, getting a weekly blowout isn't in the cards for most of us because of budget and time constraints. After Katie's hairdresser gifted her the Dyson Airwrap, she started styling her hair at home, and it's easier than she expected. "It’s so much easier to use than holding a round brush in one hand and a blowdryer in the other — and the results are much better, at least for a non-professional like me," Katie says.

$500 at Amazon

Thrive Causemetics Mascara

Amazon

$26 (20% off)

"I don’t wear much makeup on a day-to-day basis, but I treat my lashes to Thrive mascara when I do," Katie says. "It's my new go-to as my lashes get blonder — and, sadly, less voluminous — as I, um, mature. Not only does it make my lashes look super long, but it also comes off with just warm water." While waterproof mascaras are ideal for watery eyes or oily skin, it can be irritating (literally and figuratively) to remove. But Thrive's tubing technology eliminates the need to scrub.

$21 at Amazon

Bose QuietComfort Headphones

Amazon

$360 (57% off)

On long-haul flights, noisy commutes, or when listening to podcasts, Katie prefers headphones with crystal clear sound quality and noise-cancelling abilities. These ones from Bose fit the bill, and she's had them for years. They're extremely comfortable to wear (even with earrings), and they don't leave you with a headache like some too-tight models.

$169 at Amazon

CRBN Pickleball X Series Power Paddle

Amazon

$229 (35% off)

When it comes to smashing passes on the pickleball court, having the right paddle is key. The easy-to-hold grip and carbon fiber paddle on this one are standout details, but the included case is a nice touch, too. You can catch Katie acing serves with a similar paddle, which she carries with her from court to court.

$150 at Amazon

Maldon Flaky Sea Salt

Amazon

Years ago, Bobby Flay (name drop, no shame) gifted Katie a container of Maldon salt. She's been hooked ever since. You can use it to finish off pasta dishes, sprinkle it atop chocolate chip cookies, and so much more. Plus, it makes a great gift for the friend who loves to cook. Katie buys large containers of the stuff to make sure she doesn't run out.

Portable Garment Steamer

Amazon

$30 (23%)

If you’re anything like Katie, the last thing you want to wrestle with before getting dressed is an ironing board, especially when you’re traveling. Enter this little handheld steamer, a surprisingly powerful gadget considering the size. It heats up in about 30 seconds, smooths clothes fast, and folds up so neatly. It’s so lightweight and simple to operate, you might even be inspired to use it at home, too. (It’d be a huge help when steaming wrinkles out of new curtains, for example.) This guy is simple, reliable, and helps you look way less rumpled, even when you’re ridiculously jet-lagged.

$24 at Amazon

OSEA Body Oil

Amazon

"I apply this body oil while I'm still in the shower," Katie says. "I basically shake off like a dog so I'm not soaked, then I'll put this on." It's infused with seaweed, which is clinically proven to improve skin elasticity and hydration, leading to softer feeling and firmer-looking skin all over.

$52 at Amazon

Apsvo Chunky Earrings

Amazon

$18 (31% off)

These earrings remind Katie of the classic Paloma Picasso earrings from Tiffany. They’re super light and elegant-looking, and so far they haven’t turned her ears green, which is a huge win considering they cost less than $15 a pair.

Sente Dermal Repair Cream

Amazon

After getting a sample of this luxe cream from her dermatologist, Katie was hooked. "To lock in moisture, I swear by Senté cream for my face. It keeps my eczema flare-ups at bay and just makes my skin feel great," she says.

$105 at Amazon

Senté Even Tone Mineral Sunscreen

Amazon

Katie recently discovered this gentle SPF, and she loves it so much, it won a Timeless Beauty Award. She turned us all onto it, too, and we've learned the higher price tag is worth it if you have sensitive skin. This tinted SPF protects her from both UV rays and blue light, while also acting as a skin tint. Zinc oxide and titanium dioxide provide broad-spectrum sun protection without the irritation sometimes associated with chemical sunscreens, while iron oxides help defend against discoloration.

$75 at Amazon

Garlic Roller

Amazon

Katie's fingers never smell like garlic, and it's not because she doesn't cook with it — It's because she doesn't claw the peel off with her fingernails like the rest of us garlic-loving loonies. "I swear by this gadget," Katie says. Just put your cloves in the rubber tube, roll it on the counter, and the peel will come right off. No more papery garlic husks flying around your kitchen.

$8 for 3 at Amazon

Hexagonal Polarized Sunglasses

Amazon

How many of us have lost a pair of sunglasses in the ocean or accidentally left them behind at a vacation rental? *Raises hand.* After seeing them on a coworker, Katie snagged herself a pair of these inexpensive sunnies that are dead ringers for some designer specs. We hope you don't lose or scratch them, but if you do, you can replace them for only $11.

Comfy Floats Glasses

Amazon

Having a glass of wine or a cocktail while at the beach or pool is a dream, but spilling it in the sand or water is a nightmare. With this acrylic cup, you don't have to worry about tipped-over drinks ever again. You can stake it in the sand if you're on the shore, or you can let it float in the pool while you're taking an evening dip (just be sure to keep splashing to a minimum — you don't want to be drinking a chlorinated cocktail).

$10 for 4 at Amazon

Cherry Pitter

Amazon

$10 (10% off)

During peak cherry season, you'll find Katie whipping up cobblers and pies with the sweet stone fruit for as long as she can. Removing the pits can be a pain, but using this stapler-like device makes pitting cherries as easy as, well, pie.
