Updated on Tuesday, October 21, 2025: Costco’s Cyber Monday 2025 event will officially wrap up the warehouse giant’s long stretch of Black Friday and holiday savings. The sale remains online-only and exclusive to Costco members, featuring a dedicated page of limited-time offers that go live early on Monday, December 1, 2025.

While smaller in scope than the full Black Friday ad, Costco’s Cyber Monday deals typically focus on electronics, home appliances, furniture, and jewelry, often with some of the steepest markdowns of the entire season. You can see the full ad posted below.
