How does the Supermarket module work?
The Supermarket and Grocery modules work the same way as any other retail marketplace. As a Vendor, you simply list the products you have for sale and customers are able to purchase them at the fixed prices that you assign. To list products in either of the Supermarket or Grocery modules, visit the ↗ Sell Grocery & Products tab of your Vendor dashboard.
