Affiliate tracking on Membership Options Page

Hello!
I recently bought the pro version of s2members and I created a page as the “Membership Options Page” where I ve pasted 3 generated paypal buttons:
1. Service A billed as $10 per month
2. Service B billed as $20 per month
3. Service C billed as $10, single payment.

This page doesnt need any registration since its the “Membership Options Page”.

I want to be able to track any sales made by my future affiliate plugin but I dont know if this is possible since this page is not a membership page where users must first register and then pay but a free to access “Membership Options Page” where visitors just click the paypal button and send payment.

Is this do-able or do I have to change the way I receive payments, for example redirect each subscription to a separate page that has the payment button and needs to register first in order to access it?

Right, you don’t want to track sales on that page; you want to track sales with s2Member integrated with your affiliate platform. iDevAffiliate is recommended, but you can integrate with just about any affiliate platform. I would take a look in your Dashboard at this section please.
