Affiliate Marketing Secrets

If anyone has ever used this I have a couple questions that are super vague on the site.
First, it says one referral per household. Does that mean I can only refer one person per household, or that I can only get the reward from the first person I refer?
Second, it says the money is sent at the end of the month. Can I use that on their site prior to that or do I need to first wait for a check then put in bank?
