Few days later he made purchase again – and again with discount 25% code. And again I paid 25% affiliate commissions.

Question is: how long to wait till relations between affiliate and customer “wears off”? I wanted to offer special discounts to this customer – but combined with affiliate commission it makes deals non-profitable. It’s not fair to leave good customer w/o special discounts – I guess. Now I’m thinking to either remove affiliate commissions or make them alot less than 25% (like 10 or so) – which is the same thing.

A coupon is only taken off the initial payment, and not the recurring payments, correct?

And second, regarding affiliates — If were to give affiliates 10% on a sale of a recurring $10 item that billed every month, would they receive that $1.00 only once, or each month the product was billed?
