I just did this so I can help! The code for the Ready for Fun is GMOG, value is $26.00. That gets entered on the form under "I am Returning." Then down under "I am Ordering" just put in what your exchange item is that you want.

I got a $2 refund check because the outfit I picked, Butterfly Brocade (GBOP) is $24. Also don't forget to pack the undies and ponytail holder too. I almost didn't think they were part of the RFF outfit. The book itself is just part of the meet and didn't have a sep. code. Good luck!
