We were at CSA in May 09 and my wife wanted a gold Couples palm tree charm for her charm bracelet. We checked at the gift shop in the Great House and all they had was silver. We asked the woman behind the counter if they came in 14K gold.
She said they did but they did not have any there at that time. She said she would check with the gift shop at CN. The next day she had the charm for us - so if you don't see one - be sure to ask them if they can get you one from one of the other Couples.
