Research notes
The Costco Business Delivery product page is the most authoritative reachable source (brand has no independent direct-to-consumer site since it's a private-label store brand). The page gates price behind a ZIP code entry and did not render live in this session, so price is sourced from third-party Costco price trackers rather than confirmed directly on-page. The 'Specifications' and 'Shipping & Returns' tabs on the page could not be expanded during this browsing session, so any additional details in those tabs (e.g., full nutrition facts, exact ingredient list, country of origin declaration) are not captured here.
