Help Implementing Options for diffent discounts for month 1 and 2

The type of discount is a percentage discount; I failed to mention that. 
Does Stripe store the percentage discount or a value, or either, depending on the type of discount?

We send Stripe the already final discounted amount.

So, if we change the price of a plan, CBSubs will apply the discount to the new price and send that amount on to Stripe? Did I get that correct?
Thank you,
Chris

For a recurring subscription? No. Once a recurring subscription is created and subscribed to its price cannot be changed. You'd have to cancel future renewals at Stripe forcing them to manually renew into the new price to establish a new billing agreement. For non-recurring payments you can freely change the price at any time since each renewal is manual.

Thank you for the thorough explanation, Kyle. It's much appreciated.

Hi Kyle,
Sorry to have to come back and ask questions, but my developer is almost ready to have the subscription system functioning perfectly. He ran into a problem when adding a custom header creation option to the second month of Plan 1. Here is his explanation and a screenshot of the transaction. Please let me know if you need anything from us to help us resolve this issue. He says "We are facing an issue with the Stripe recurring checkout calculation in CBSubs. Scenario: Plan 1 has an initial amount of $23 and recurring amount of $69 Plan 2 is a fixed one-time package of $150 When both plans are added to the same basket, the invoice total becomes $173, but Stripe charges: $69 correctly for the recurring item $104 instead of $150 for the fixed-price item It seems the recurring basket calculation is affecting the one-time package amount during Stripe checkout processing."
Thank you in advance for your help,
Chris
