There are 2 things to note:
- Affiliate link will open for a specific product. But if the user goes back to home page or reopens website and buys some other product, even that will get tracked and counted, so don't worry.
- All pending orders (people who have filled details but not paid) will be automatically deleted in 2-3 days. These orders will be seen under affiliate commission for 3 days. So real commission will be visible after 3 days.
