Affiliate sales is a report that shows all sales that take place via the affiliates that you have created.
To enter your affiliate sales report select "Reports" from the top bar and "Affiliate sales" from the drop down list.
The report will, by default, show you all affiliate sales for the current month, from all of your affiliates.
You can filter the report by affiliates by selecting the "All" drop-down list in the upper left hand corner.
You can also select the date range you would like to look at by selecting the date field in the top right hand corner.
