Products that can sell in Retail Store but not Web Store?

[Terence Ng]

How to add products so that I can allow to sell in Physical Retail Store but not on Web Store?

What is the best way?

How about separate the products into 2 Catalogs - Common and Restricted?  Add only Common Catalog to Product Store Catalogs in Catalog Manager > Stores > Catalogs?

Could I control it on Products level rather than on Catalogs level?  How to use Catalog Manager> e.g. Product For: Gift Card Activation [ID:GC-001] > Facitlities?

I have found some information:

But still there is no info regarding to control in Products level.
