My partner and I have each a credit card offering sign up bonuses (amex and anz). We got the bonuses as we spent enough on the first 3 months. But now I want to move to another credit card offering a sign up bonus too, and close the old ones. When can I safely close those two first credit cards, without making amex and anz ask the bonus back? For the amex for instance, we did not even pass the 3 first months before we got the signup bonus unlocked.
Thanks a lot
