Costco’s 2025 Black Friday ad teases major tech and home deals

Costco's holiday deals for this year have started, and a leaked ad has shown that their holiday discounts start on Halloween. This puts Costco in line with big retailers like Best Buy, which is also getting ready for early Black Friday sales around the same period.

The scanned ad shared by Costco Insider suggests that their 2025 sale will feature a huge selection of items. You can enjoy low warehouse prices on all your favorites, including electronics, appliances, clothing, shoes, jewelry, toys, and more.

You can find best Black Friday deals on electronics from brands like Sony, Samsung, LG, Microsoft, Bose, and Sonos.

The leak also hints at deals across almost every department, marking this as one of Costco's biggest Black Friday events of the year. You can find some discounts, like $120 off on PS5 consoles and savings on Apple devices such as MacBooks and AirPods. The actual price drops on Apple products aren’t clear yet, but their inclusion hints at a solid selection of tech deals.

Another standout deal from the leaked ad is for the Sonos Arc Ultra soundbar, which is expected to be discounted by $220. This is a significant price cut compared to the smaller $100 discount it had during Labor Day weekend.

With sales running until Cyber Monday, the Black Friday weekend seems like the perfect opportunity to snag popular products or special deals.
