I have set discount codes for orders on my website. When people order, I know who they were referred from because of the discount code they enter. For example, if the discount code HAYLEY is entered, I know HAYLEY referred the sale and therefore I know I should give HAYLEY a commission on the sale. When getting the email from e-junkie for an order placed with a discount code it doens't tell me what the discount code was. This makes it impossible fro me to track who the sale was referred from. Is there any way to see that somewhere? Can it be added to the email I receive?
