Commerce - Require login only for specific products I'm building a commerce site using drupal commerce. I know how to have anonymous users checkout, I know how to require login before checkout, but I can't figure out how to specify for each product if it requires a login or not...
You could use Rules to enforce login when the product is added to the cart.

e.g


Event: Before/After adding product to cart
Conditions: if user is not logged in (i.e. uid=0) and product match (e.g SKU matches)
Action: Redirect to user/login?destination=cart


Something like that could suffice.
