Must sign-up / have a swagbuck account, and open up a new account for gamefly. Mine credits instantly, for a profit of $15 (in form of paypal or amazon giftcard) + the 2-month service. The 2500 Sbs = $25 in cash. The Hulu trial is delivered via email right after the payment.
But as always, document / screen-shot everything for a possible ticket if credit did not apply.
