Yes, customers can add promotion codes through the Customer Billing portal, but you're only allowed to add them when other changes are made to the subscription (like an update to quantity or a change in price)

Perfect – thank you @lilac rapids 🙇‍♂️

Might I suggest adding this information to the page linked from that "Learn more" link in my screenshot – https://stripe.com/docs/billing/subscriptions/coupons/codes

Have a great day or whatever 😄
