Costco has long been a go-to destination for bulk groceries, household essentials, and those famously inexpensive hot dog and soda combos. But the warehouse club also carries a surprisingly wide range of consumer electronics, from smartphones and laptops to televisions and smart-home gear. While everyday prices at Costco are often competitive, the store regularly runs promotions that make certain items even more attractive. August 2026 is no exception, with several electronics seeing meaningful price drops for a limited time.

Below, we break down four standout electronics deals at Costco this month, including the key facts you need before making a purchase. Each deal has a specific end date, and inventory can vary by location, so it is wise to act quickly or check your local warehouse online.

Arlo Ultra camera bundle: Whole-home security at a discount

A complete home security system can quickly add up, especially when you need multiple cameras to cover entry points and outdoor areas. Costco currently offers the Arlo Ultra bundle, which includes three Arlo Ultra third-generation HDR 4K outdoor smart cameras and the Arlo Ultra SmartHub. The package is priced at $349.99, down from $449.99, saving you $100. This promotion started in late July and runs through Aug. 16.

Each camera in the bundle has a 180-degree field of view, motion detection, auto-zoom, color night vision, and subject tracking. A magnetic mount simplifies positioning, while a built-in siren and spotlight can help deter intruders. The camera operates on a swappable, rechargeable battery, and a low-power mode lets it continue functioning as a snapshot camera even when the battery is too low for video recording. Two-way audio with wind and noise cancellation is also built in, making it easy to speak to visitors or delivery drivers.

The included SmartHub creates a dedicated wireless network for the cameras, operating on its own frequency. According to Arlo, this design reduces interference from other household Wi-Fi devices, increases range, and improves overall performance. Buyers also receive a free one-month trial of Arlo’s Early Warning System subscription, which adds advanced detection features. Customer reviews on Costco’s website give the system 3.9 out of five stars based on more than 45 ratings. Most users praise the picture quality and field of view, though some report difficulties with the battery charging process or the initial software setup. For shoppers looking for a complete outdoor security solution, this bundle represents one of the better values available this month.

Bose SoundLink Home: Stylish sound for less

Bose is a name synonymous with premium audio, but that quality often comes with a higher price tag. Costco’s August sale takes $50 off the Bose SoundLink Home Bluetooth Speaker, bringing its price from $179.99 to $129.99. The discount applies to all three color options: Cool Gray, Warm Wood, and Light Silver. The sale remains active until Aug. 23.

The SoundLink Home is a battery-powered wireless speaker that supports Bluetooth 5.3 and delivers up to nine hours of playback on a single charge. A built-in microphone allows hands-free calling and voice assistant access from your smartphone. One of the more compelling features is the ability to pair two SoundLink Home speakers together for true stereo sound, with separate left and right channels. This makes the speaker a flexible addition to a home office, kitchen, or bedroom.

Design-wise, the speaker features an anodized aluminum shell with a fabric front, giving it a sleek, modern look that fits into most living spaces. Bose says it produces "crisp, clear sound with deep bass," a claim supported by many customer reviews. On Bose’s own website, the SoundLink Home holds a 4.6 out of five-star rating, with users praising the audio quality, feature set, and design. The few negative reviews mention that the charging cord can look somewhat awkward when plugged in, but most owners are satisfied with the overall performance. If you have been considering a mid-priced Bluetooth speaker, this discount makes the SoundLink Home an easy recommendation.

Bose Ultra Open-Ear headphones: Premium open-ear audio with a bonus gift card

Bose’s wireless speaker lineup is well known, but the company also makes high-end earbuds. The Bose Ultra Open-Ear true wireless earbuds are currently on sale at Costco for $199.99, down from $299.99. In addition to the $100 discount, customers receive a $50 gift card redeemable on the Bose Promotion website. This deal ends Aug. 9, making it the shortest window of the four featured promotions.

These earbuds use an open-ear design, which means they do not completely block outside sound. That makes them especially suitable for outdoor activities like jogging, cycling, or walking, where situational awareness is important. The earbuds carry an IPX4 water-resistance rating, so they can handle sweat and light rain. Each bud has a built-in microphone, and the battery is rated for up to seven hours of listening time. The included charging case provides additional power on the go, and a USB-C cable is supplied for recharging.

The Bose Ultra Open-Ear earbuds have earned a 3.9 out of five-star rating on Costco’s website from more than 175 customer ratings. Positive reviews frequently mention the excellent sound quality for music, while some users are less impressed with voice call quality. Fit and comfort are also a point of debate among reviewers, as open-ear designs do not fit every ear shape equally. For those who prioritize awareness and comfort during workouts, the combination of a steep price cut and a gift card makes this deal particularly attractive.

JBL PartyBox 120: Big sound for gatherings

JBL is known for its portable Bluetooth speakers, but the PartyBox 120 is a different kind of beast. This massive speaker measures 22.4 by 11.7 inches and is designed to power parties, backyard gatherings, karaoke nights, and other events. At Costco, it is currently available for $349.99, a $100 reduction from its usual price of $449.99. The sale runs through Aug. 16.

The PartyBox 120 is built with entertainment in mind. It features dual microphone and guitar inputs, and a wireless microphone is included in the box. That means you can set up a karaoke session or plug in an electric guitar for an impromptu live performance. The speaker also has an integrated light show that syncs with the music, creating a club-like atmosphere in your home or yard. JBL’s AI Sound Boost feature analyzes audio in real time and adjusts the speaker’s output for maximum sound quality.

Durability is another highlight. The speaker is splash-proof, so it can handle outdoor use without worry. It supports Auracast, allowing you to pair it with other compatible JBL speakers for an even larger soundscape. Battery life is rated at up to 12 hours, ensuring the music keeps going well into the night. On Costco’s website, the JBL PartyBox 120 has a 4.5 out of five-star rating. Customers frequently compliment its loud volume, thumping bass, and extensive feature set. The handful of negative reviews are mostly related to shipping and packaging issues rather than any consistent flaw with the speaker itself.

With multiple electronics on sale, Costco continues to prove that it can be a smart place to shop for tech. Whether you need a security camera system, a portable speaker, open-ear earbuds, or a party powerhouse, August 2026 offers a chance to save on quality products. Just be sure to mark the expiration dates on your calendar, because these discounts will not last forever.
