I’m sorry, but I’m not sure I understand what you are trying to do. Let me see if I get it:
- first month charge $10.99
- second month charge $10.99
- third month onward charge a higher amount.
If so, then no. The trial can only be one period and then the regular ones kick in. At the moment is not possible to do two charges at one amount and following others at another, only the first charge can be different (the initial term) from the following ones (regular terms).
It isn’t impossible to do with custom code, but s2 Member doesn’t include it. You’re actually the first one that I remember asking about it, but it’s something do I do have the idea of making possible. I’m adding your vote towards this feature in my list.
If I misunderstood your question, could you please clarify it?
