You can now see inventory information of a specific product and its location (be it in a nearby store or a warehouse), separated line for line between stock and stores. Swipe right on the product while it is in the cart, then tap "Info". Alternatively you can long press the product in the product section of the app to bring up the Product Information window.
The sections are divided between Warehouses, Stores and Nearby stores and each section will show you how many of this particular product are available at their respective location.
See information here on how to configure nearby stores.
