Need to hide some collections and thus products inside them to the general visitor.
These collections will be visible to selected customers only.
Customers will have to login with their account which have been granted access by us at the backend by tagging that customer with a keyword. New customer may create an accounts and than we will decide to grant access or not.
The products under the hidden collection should not be visible anywhere on the store, to the general visitor.
To the general vistor there will be no trace about existence on any such collection.
This is bascially a retail and wholesale trade situation.
