Affiliate program signup in checkout

[sbazartejr]

Users who are purchasing a key to a lock through the Wordpress plugin should be able to relate their wallet address or Unlock account with a unique code, essentially signing up as an affiliate to the lock to receive a referrer fee upon code use at checkout. Additionally, the code could also provide a discount rate to any user that is given the code, such that there is mutual benefit to input of said code.

Case:
User1 is checking out using the Wordpress plugin; a prompt to sign up as an affiliate and/or use a referral code is included on checkout page. User1 inputs a referral code created by user2, which provides a discount rate of x to user1's key purchase and distributes a referrer fee of y to user2.

Alternatively, I know @julien51 mentioned customization of URL's; Could we give each affiliate their own subdomain under our Wordpress webpage, and track how many purchases come from each subdomain? Next we could schedule consistent 'snapshots' of data, and distribute a referral payment manually from the lock manager wallet.

Very interested in exploring this use case for 16 locks that will be actively marketed come next month.
