Affiliate Commissions for Future Pruchases?

If I refers a customer and the person makes 1 purchase or no purchase and just registers a account. Will I get affiliate commissions for future purchases of the customer or just initial purchase commission?

You will get a commisions only for the first purchase or first cedit from your referall of any customer. So for example you refer 1k customer and they have made their first purchase then you will get for all 1k customer. If a customer purchase 500$ at first purchase then you will get commisions for that 500$. Hope you understand. Thanks
