I have a series of different parent subscription alternatives - each of which enable users to have the same basic access to a site for different periods of time:

eg.
Plan A - 1 year subscription
Plan B - 6 month subscription
Plan C - 3 month subscription
Plan D - 1 month subscription

Now I'd like to add a Child Plan Z which will give a subscriber to it added access that they don't have in any of the plans noted above.

Users have to have subscribed to one of the Plans above in order to have access to Child Plan Z. Child Plan Z will work with any of the four parent Plans (A,B,C,D).

Given all this, I'm still fuzzy how I configure Child Plan Z so that it is only accessible by users when they are logged on and they have an active subscription with one of the four parent plans noted above.

I am kinda looking for something similar...

I would like to have for example 3 plans...

1. Paid Membership-1
2. Paid Membership-2
3. Registered User (for store)

I would like to do this so if a guest buys from the store it is easier to throw them into a membership, with the store account the user will maintain their order history, and lastly it will help integrate CB with VM.

Is the best way of doing this by using a FREE parent plan?

Thanks.

Thanks Krileon -

You cleared up three key things for me:

1 - Child plans are exclusive to their parent. (e.g. the same child can't be associated with more than one parent)

2 - Parents must be exclusive and allow upgrades to prevent duplicates. Child plans should be non-exclusive to they will be optional

3 - And the child plan should be set with Allow Registration to No, which will keep the child plans to only appear when a user is logged in

As for iapmos' question, I think that this suggestion is applicable regardless of whether the parent is FREE or not
