Cyber Monday is almost over, and Costco's notable deals expire at midnight. You’ll find sales on televisions, phones, vacuums and more, but don’t wait to shop — many of them end tonight.
I cover the biggest sales of the year as a writer for NBC Select, so I know how to find deals that are actually worth buying. I spent weeks combing through thousands of discounts to find the best Cyber Monday deals at Costco — each one I recommend below is highly rated and 20% off or more. When possible, I ran deals through price trackers to make sure they’re at their lowest price in at least three months or the lowest price ever. I’ll frequently update this list throughout Cyber Monday.

Best Cyber Monday Costco deals
Costco is an authorized Apple seller, and these earbuds are a favorite amongst NBC Select editors. They have two listening modes — transparency and active noise cancellation. Regardless of what mode you’re in, the earbuds lower the audio volume when you’re speaking. You can also tap them to control music or calls.
You get two toothbrushes in this set — making it an ideal purchase for partners. The toothbrushes have a pressure sensor that alerts you if you are brushing too hard, a two-minute smart timer and a brush head replacement reminder. The set also comes with three brush heads, two chargers and two travel cases.
Intended for one- to two-bedroom homes, this security kit can protect up to three windows or doors with the included contact sensors. It also comes with a motion detector that can be used in a hallway or room.
Use this portable vacuum to tackle pet messes on carpets and upholstery. It comes with several attachments, including a hair removal tool and a self-cleaning stain tool. It also comes with a bottle of OxyClean Spot and Stain Urine Eliminator.
This is one of our favorite hair dryers — it’s efficient and minimizes heat damage by automatically checking and adjusting its temperature 40 times a second, according to the brand. It comes with five different attachments, including a diffuser, a concentrator nozzle, a wide tooth comb and a flyaway tamer.
I have a few of these in my garage, and they keep big bins of stuff — think holiday decor, extra hoses and gardening tools — organized and off the floor. The metal racks can hold five large bins. One thing to note: The rack is only compatible with Greenmade 27 Gallon Bins, which are also currently on sale.
This stainless steel trash can has a motion-sensor lid that opens when you stand in front of it. It fits 13-gallon trash bags and has a removable plastic liner that pulls out easily for cleaning. The finish is also fingerprint-resistant, according to the brand.
One of our favorite pieces of stainless steel cookware, the outside of the pan and its lid are stainless steel, while the inside is non-toxic titanium. This pan is oven-safe up to well above 500 degrees and it comes with a steamer basket, lid and spatula.
De’Longhi makes some of our favorite espresso machines, and this automatic model has a built-in grinder with 13 settings and a milk frother for lattes and cappuccinos. You can also choose between three intensity levels for espresso, coffee, Americano and over ice, and most of the parts are removable and dishwasher-safe.
NBC Select editorial director Lauren Swanson has used these to run multiple marathons and says the battery life is exceptional — they’ll run for up to 8 hours on a full charge. They are also lightweight, water-resistant and have built-in dual noise-cancelling microphones.
The Roborock QX Revo uses smart mapping to determine the best cleaning route for vacuuming and mopping. It has a rubber brush that prevents hair from tangling around it and strong suction to pick up even the tiniest debris, according to the brand. It also has a mop mode, which uses dual mops to spin and exert consistent pressure to thoroughly clean floors. When not in use, you can store it in the docking station, which has an auto-emptying function.
This 2-in-1 floor washer is exclusive to Costco. It mops and vacuums at the same time and works on hard floors like wood, tile and vinyl. On a fully charged battery, you get up to 25 minutes of nonstop run time and you get real-time battery updates on the LED screen. It also has a four-stage HEPA filtration system, a self-cleaning cycle and two tanks — one for dirty water and one for clean water.
The Bose Soundlink Flex is 7.9-inches wide and 3.6-inches tall and it outputs high-fidelity audio that is balanced and clear according to the brand. It has multiple audio modes — including stereo mode and party mode for fuller sound output. The speaker has a 12-hour battery life on a full charge and can connect to devices via Bluetooth that are up to 30 feet away.
Sonos is an NBC Select staff-favorite brand, and tech reporter Harry Rabinowitz loves the Sonos Era 100 speaker because it’s compact, yet delivers sound that’s clear, crisp and loud. It also has both Bluetooth connectivity and Wi-Fi streaming for flexible listening options. This set includes two speakers for a great price.
Delsey Paris is one of the best brands for lightweight luggage, and this two-piece set includes a carry-on and a large spinner suitcase. They both have a scratch-resistant hardshell exterior for protection, shock-absorbent wheels for smooth rolling and interior pockets for organization. The larger suitcase also has a TSA-approved combination lock and an expandable design.
Legos aren’t just for kids. NBC Select Staff loves the brand’s Botanicals sets because they’re fun to build and look great on display. This flower arrangement comes with 1,161 pieces to create a colorful bouquet of rearrangeable blooms in a pedestal vase — and unlike real flowers, they don’t require any upkeep.
In addition to regular blending, this blender has smoothie and hot soup settings. The blender also has a self-cleaning mode — just add a drop of dish soap and some warm water, run the program and rinse it out. The blender has a 64-ounce container, allowing you to mix large quantities and it comes with a tamper that allows you to push down ingredients for a better blend.
These over-ear headphones have up to a 24-hour battery life and come with a carrying case, making them a great option for travel. They also have active noise cancelling and soft padding around the ears for comfort.
On our list of best water flossers, the Philips Sonicare Cordless Power Water Flosser comes with two tips — standard and quad, which helps cover more surface area. It also has an 8-ounce reservoir, which holds enough water for one minute of flossing, according to the brand. With this set, you get two water flossers, making it a great buy for couples.
Having a party? This large portable speaker delivers high quality audio and comes with a wireless microphone for speeches, karaoke or anything else you may need. It has up to 12 hours of battery life on a full charge and the front has multicolored lights that flash while you play music.

All of my recommendations above are based on NBC Select’s previous coverage and reporting, including products the NBC Select staff tested firsthand.

When possible, I ran deals through price trackers like CamelCamelCamel to prioritize highlighting products that are at their lowest price in at least three months or lowest price ever.
