Configuring Catalog Price Scope
If you have a multisite installation, make sure to configure the price scope before you create your shared catalogs. The price scope can be set to “Global,” or “Website”. However, it can be set only at the beginning of the setup process. The Website chooser appears during Step 2 of the shared catalog setup.
To configure the price scope:
On the Admin sidebar, tap Stores. Then under Settings, choose Configuration.
In the sidebar under Catalog, choose Catalog.
Expand the Price section.
Set Catalog Price Scope to “Website”.
