For new customers, GameFly offers a 30-day trial for free. That's tied with our June mention as the longest free trial we've seen from GameFly. Similar to Netflix, GameFly sends you up to two game rentals at a time with free return shipping. It carries games for the Xbox 360, PlayStation 3, Nintendo Wii, and more.

You must cancel the subscription before the trial is over or you will be billed for one month of service, currently $15.95 a month.
