The online/orders guide separates Costco Logistics, third-party carrier issues and In-Home Installation rescheduling. These are guide-selection signposts; consult the destination’s exact scope before relying on a branch. No live route or outcome follows from a hub link.\n\n**Navigation inspection:** **2026-10-05T08:11:26Z**; recheck these links after a changed destination, before reliance or by **2026-10-12T08:11:26Z**. This update replaces only the membership and online/orders pins. The company table, local-warehouse advice, original source URL and **October 1, 2026** source baseline above remain unchanged. This is a Wiki5 navigation check; it does not renew telephone-source clocks, hours, menus, holiday availability or service outcomes. Business Center and technical/warranty pins and their historical check clocks remain unchanged.\n\nTen author navigation decisions were rechecked; a distinct same-operator checker verified the exact citations and five additional reader boundaries on **2026-10-05T08:16:36.153Z**.
