For new GameFly members only, Groupon offers a GameFly 2-Game 30-Day Subscription bundled with a $5 GameFly Credit for free. (You'll receive a voucher to redeem at GameFly's website.) That beats our July mention (which lacked the $5 credit) and is a $28 savings assuming you use the credit. This plan entitles you to two games or movies at a time. The credit can only be used to buy a used game and requires a minimum purchase of $10. (It must be used by February 28.)

Note: After the free subscription ends, you'll automatically be billed $22.95 per month unless you cancel the service.
