Hello,
I'm trying to understand what happens when a subscribed customer of a subscription A purchases a promotional offer for the same subscription A.
Let's say the product is a yearly subscription priced at $100. When the month 7 starts (6 months remaining in the regular subscription period), I send the user a promotional offer for the same product but priced at $25 for the first year (100$ afterwards) and he accepts the offer.
Is the promotional offer started only at the end of the current year (after the 6 remaining months) or is it started immediately and he gets a pro-rata refund for the 6 remaining months?
Thanks.
