Costco is known for bulk groceries and household items, but its electronics department often delivers surprising value. In July 2026, the warehouse club is offering deep discounts on three specific electronics that cater to home security, entertainment, and networking needs. While the Fourth of July sales have passed, these deals remain attractive for members and non-members alike. Non-members can purchase online but face a 5% surcharge, making a $65 Gold Star membership worthwhile for larger purchases. Costco also provides a generous 90-day return policy on electronics and extended warranty options.
