The Fourth of July sales have ended and the excitement of America 250 celebrations has passed, but that doesn't mean you can't still find excellent deals on electronics. Costco may not be the first retailer that comes to mind when shopping for a new television, laptop, or security system, but the warehouse store actually carries a wide selection of electronics and frequently offers special discounts on top of its already competitive prices.
This July 2026, Costco has several noteworthy electronics deals worth considering. While some of these offers are available to anyone shopping online, non-members will incur a 5% surcharge on purchases made through the website. A basic Gold Star Costco membership costs $65 per year plus applicable sales tax, and for high-priced items, it often makes financial sense to join. Additionally, Costco provides a generous 90-day return policy on electronics including TVs, tablets, wearable devices, and more. The store also offers extended warranties on many products for an additional fee. Product support and troubleshooting guides are accessible online, and you can even schedule a professional mounting service for your new TV. So stash the sparklers away for next year and head to your local Costco or visit their website to take advantage of these deals.
SimpliSafe Security System
If you've been considering adding a security system to your home, this deal may be worth jumping on. The 13-piece SimpliSafe Security System includes two outdoor security cameras from the company's Series 2 line. Available online only, this system is reduced by $150, bringing the total price to $199.99. There is a purchase limit of two per Costco member.
SimpliSafe promotes this system as easy to set up straight out of the box. Your purchase includes three months of free professional monitoring, which provides an added layer of protection without an immediate subscription commitment. The outdoor cameras feature an ultra-wide 140-degree field of view and record at 1080p resolution. For nighttime security, these cameras incorporate color night vision assisted by a built-in spotlight, allowing you to identify intruders even in complete darkness. Homeowners have the flexibility to install the cameras wirelessly using the included rechargeable battery, or they can opt for a wired connection using outdoor power cables. It's important to note that if you later decide to subscribe to a paid monitoring plan with advanced features, the outdoor cameras must be wired with the supplied power cables to meet system requirements.
The kit further includes eight entry sensors designed for doors and windows, a motion sensor capable of detecting movement up to 35 feet away, and a base station that serves as the central control hub for the entire system. The SimpliSafe Security System is compatible with both Amazon Alexa and Google Assistant, allowing for voice control and integration with smart home ecosystems. The system carries a one-year warranty. In recent years, SimpliSafe has been recognized as one of the best home security systems available without a mandatory long-term subscription, making this an attractive option for budget-conscious homeowners who want reliable protection.
Samsung 55-inch QLED TV
This deal is exclusively for Costco members and includes a 55-inch Samsung QN70H 4K Mini LED smart television bundled with a three-year Allstate protection plan for $749.99, with free shipping. This television utilizes QLED technology, which employs an LED backlight shining through a quantum dot layer to produce vibrant colors and high brightness. The specific model goes a step further by incorporating mini LEDs — smaller individual light sources that allow for more precise local dimming, resulting in sharper contrast and deeper black levels compared to standard LED TVs.
The TV also features an AI processing system that intelligently analyzes the content being displayed and automatically adjusts picture and sound settings to optimize the viewing experience. Whether you're watching a fast-paced action movie, a nature documentary, or a live sports broadcast, the AI works to enhance clarity, color accuracy, and audio presence. Samsung's Motion Xcelerator technology ensures smooth, blur-free motion even during highly dynamic content like sporting events or video games with rapid movement. Additionally, the TV offers 4K upscaling, which improves the appearance of lower-resolution content so that it looks closer to native 4K quality — a useful feature for those who stream older shows or watch standard-definition DVD content.
Gamers will appreciate the Samsung Gaming Hub, which consolidates games from consoles, cloud streaming services, and mobile apps into one convenient interface. The hub can even recommend new games based on your preferences. The TV also includes a range of sound processing options, such as an adaptive AI-driven setting that adjusts audio based on the environment, a voice amplifier for clearer dialogue, and motion-based sound that tracks movement on screen to create a more immersive audio experience.
The included Allstate protection plan extends coverage beyond the TV's basic two-year warranty, providing a total of five years of protection against defects and certain types of damage. This TV is part of Costco's Direct Savings program, meaning that if you purchase multiple eligible items from Costco Direct in the same order, you can receive additional savings. When choosing a new television, factors such as screen size, panel technology, connectivity options, and smart features all play a role, and the Samsung QN70H offers a compelling combination of advanced features at a discounted price.
TP-Link Deco Whole-Home Mesh System
If you experience dead zones or inconsistent Wi-Fi coverage in your home, a whole-home mesh system may be the answer. This TP-Link Deco AX3000 mesh system includes two indoor routers and one outdoor router, all supporting Wi-Fi 6 technology. Together, the three units can cover up to 7,000 square feet, including outdoor spaces such as patios, decks, or pool areas. The system delivers what the manufacturer describes as seamless Wi-Fi coverage, eliminating the need for range extenders or complicated network configurations.
Currently priced at $139.99 after a $40 discount, this solution offers substantial value for households with connectivity challenges. Costco members are limited to five units per order. Each router can achieve speeds up to 3.0 Gbps with Wi-Fi 6, which not only provides faster data transfer but also improves performance when multiple devices are connected simultaneously. Setting up and managing the entire network is handled through TP-Link's Deco app, which offers a user-friendly interface for adjusting settings, checking network status, and prioritizing devices.
The system is also compatible with TP-Link's HomeShield network security package, which provides antivirus protection, malicious content filtering, and other security features to safeguard all connected devices. The indoor routers individually cover up to 4,500 square feet, while the weather-proof outdoor router extends coverage up to 2,500 square feet in exterior environments. The outdoor unit is designed to withstand rain, heat, and cold, making it suitable for year-round use.
TP-Link's Deco AX3000 isn't the right solution for everyone, but mesh networks are particularly beneficial in several scenarios. If you live in a large home with multiple floors, have many active devices such as smart home gadgets, gaming consoles, and streaming boxes, or frequently encounter dead zones in areas like garages, basements, or backyards, upgrading to a mesh system can significantly improve your internet experience. Traditional single-router setups often struggle to maintain consistent signal strength throughout a large or oddly shaped home, whereas mesh systems use multiple nodes working together to create a unified network. The inclusion of an outdoor router in this kit further extends coverage to areas where Wi-Fi is often weakest, such as a patio where you enjoy streaming music or a poolside area where guests connect their devices.
