Costco Weekly Ads & Flyers

Costco operates a global warehouse network with a heavy concentration in North America, maintaining hundreds of locations across all 50 U.S. states, Puerto Rico, and every Canadian province.

**Regional Variations**

• Consequently, a weekly ad displayed for one region may not reflect the specific stock or sales active at a warehouse in a different state or province.

**Regional Groupings**

• To ensure accuracy, Costco’s promotional materials are generally categorized by the following operational zones:
• * **United States:** Divided into regional divisions (e.g., Northeast, Southeast, Midwest, Northwest, and California) which dictate localized coupon books and warehouse-specific savings.
• * **Canada:** Operations are segmented by province, with distinct flyers issued for Eastern, Western, and Atlantic Canada to reflect regional product availability.
