Join the rewards program to earn free gift certificates. For every 100 points earned (minimum allowed amount of bonus points to convert), you obtain a $10 gift certificate. For example, if you have accumulated 250 points, you can convert your points for a $25 gift certificate. As an alternative, you can also use your bonus points to become a PREMIUM member. This will entitle you to automatically receive 10% discount on all future purchases. Click through to sign up.
