Verified Retail Merchants in the U.S. Can Add Links to Their Online Store to Their Google Business Profiles
https://blog.googleAlong with the announcement that you can now list your products on Google for free around the world. Google also made a few other announcements
Retailers can also opt-in to free local listings in the Merchant Center, enabling your in-store products to appear in free listings across Google surfaces, like Search and the Shopping tab.
They also mentioned that verified retail merchants in the U.S. can add links to their online store directly to their Business Profile on Google, so shoppers can easily place a pickup or delivery order for the holiday season when researching local businesses. I am not sure if this is the same as the blended map pack + product listings or of this will start to show up in the location panels in the SERPs.
