A LITTLE PREPARATION HELPS
Before you get in touch
Looking for the right team at Costco? The listing separates contact destinations for orders, products and store assistance. Check the retailer’s return instructions before mailing anything back. The date attached to each route belongs to its source review, rather than to the page design.
Suggest a contact correction- Check the retailer’s return instructions before mailing anything back.
- If a parcel is late, compare the retailer’s order status with the carrier’s tracking record.
- A purchase made through another retailer may need to be handled by that original seller.
