Is is possible to redeem more than one gift certificate at one time?
Unfortunately it is only possible to apply one Gift Certificate code per order. However, ytou can send us an email, provide us with your username and ask us to combine them for you.
We can combine all of your Gift Certificates to one as lomg as they are not Render Rewards.
Just send your email to firstname.lastname@example.org and we will be more than happy to assist you with this.
