It is not yet fully implemented but the plans on how it should work are finished by now. You will be able to fetch a full link to the signup page from control panel with your anonymous affiliate code included.

The new customer get's the same discount as anyone else but you will make the profit and we get a new customer so we can continue to expand and lower our prices for everyone.
