You recently launched a new line of organic protein bars with the plan to sell the bars at a popular large supermarket. What extension should you use when setting up your Performance Max for shop goals campaign?

For a product sold at a popular large supermarket, an "Affiliate location extension with a Google-curated chain" is the correct choice. This extension type is specifically designed for manufacturers or brands that sell their products through large retail chains, helping users find nearby stores carrying their items. "Affiliate location extension with a Global Location Group" is incorrect because Global Location Groups are typically used for a brand's own stores, not third-party retailers. "Location extension with a Google-curated chain" and "Location extension with Business Profile" are incorrect because standard location extensions are for businesses with their own physical storefronts, not for directing customers to third-party retailers selling their products.
