Yes, how thoughtful of you!
When purchasing a Gift Card or Gift Subscription from the Gifts Tab, after you elect the amount or frequency, there is a section headed “Personalize.” Enter your recipient's email, when you would like the gift sent and what you’d like the gift note to say. This gift note will be displayed in the email to your recipient containing the Gift Card or Subscription code on your selected email date. The same process will be applied to mailed gifts.
If you're sending a gift, you can enter a Gift Note in the Checkout.
Under the "Billing Info" heading, you will see the "Finishing Touches" heading.
Check the box that says "Is This A Gift?" to show the field for your gift note. Simply enter your name and a gift note to be included with your order.
