Hello All,

I am trying to determine if the following is possible. Lets say I am selling a comic book. I want to sell individual copies of the current issue, but I also want the option to sell a subscription, which is a copy every month for a year.

Independently, these are easy to setup except for one thing, the quantities. I have only printed a certain amount of the current issue, and an order for the subscription should decrease the available quantity for the current issue, because a subscription starts with the current issue.

How do I have two products share a single quantity?

Thanks in advance,

Whit
