GameFly Dollars issued through the GameFly Rewards program expire 90 days after being issued. For example, the 5 GameFly Dollars you receive for reaching Level 1 (3 months) will expire just before you receive another 5 GameFly Dollars for reaching Level 2 (6 months).
Percent-off discounts you've earned through the GameFly Reward program do not expire. They can be used for Buys and Keeps on any used game as long as you remain an active GameFly member.
