Say we've setup a Stripe Subscription plan. i.e. $30/mo. (Note: the billing/account info is stored on Stripe.)
Let's say we want to offer the option to the customer to buy a year of the service upfront, and if they do, they only pay $25/mo (i.e. $300).
Is there any way to conceptually link the "paid upfront" payment, and the Subscription plan? There'll related, except the second one is simply being paid up front, and at a discount because of it.
Or is the second situation simply an unrelated charge to the setup plan/subscription, and just submitted as a charge object?
(I want to make sure I'm organizing payments in Stripe the best way).
