A multi-store feature enables you to run more than one store from a single nopCommerce installation. This means you can host more than one frontend store on different domains and manage all admin operations from your single administration panel. You can create unique online stores for multiple brands, products, B2B, B2C, affiliates, co-branded stores and more. You can also quickly launch micro-stores for promotional campaigns.
The most convenient feature is that every online store shares a single database: you can share catalog data between stores, and your customers can log-in to all of your stores using the same credentials.
