Drupal commerce - purchase a product at registration I'm trying to use Drupal Commerce for a subscription site that will have only one product to purchase - a subscription to a service.

I'd prefer if a user could either do product subscription as a part of user registration, or immediately be redirected. Currently I'm trying the redirection with a rule to a custom order page (which I'm creating with rules), however rules doesn't seem to know what the order id is of the created entity.

So I'm either looking for a way to fix that, or another solution that I may have missed. Basically I want registration to be the easiest thing possible.
Figured this out - apparently you have to add the action, "save entity" after you create it, and also force it to save immediately.
