A large number can be earned as Signup Rewards. You can view these under "Player>Rewards>Signups".
You can also acquire these once a month by validating your e-mail and making sure you have e-mail updates enabled.
They are occasionally added as a supplemental payment reward. Check out the Credit Purchasing Page to see if one is on offer.
