PERSONALIZE YOUR CODE ~ when checking out, leave a note what code you want the recipient to use. There can be letters and/or numbers but no spaces (ie: KATEYOUROCK, IHEARTYOU, HAPPY100, etc) I'll enter the code into our database, and voila! It's ready to go. I will send out a confirmation email once it's live (within 24 hours).
Include your self-made code in a nice little card, and be a gift-giving hero <3
