There may be a few reasons for this:
1 – you had cookies blocked in your browser (as the affiliate link and banner sales are tracked via the affiliate username saved as a cookie so if cookies are blocked the sale doesn’t get tracked for the affiliate account);
2 – you forgot to use your affiliate link;
3 – you used another affiliate link (accidentally or by mistake) so the sale got tracked for another affiliate account;
4 - the order got tracked via another affiliate cookie that had been saved before (as commission is tracked via the first saved cookie so one should clear cookies and then click own affiliate link to purchase).
In case the order was not tracked via another affiliate cookie we will refund the commission if you email us at firstname.lastname@example.org and provide us with the order id.
