Ok, I gave my Disney rewards card with only about $12 left on it to my sister in law to use when they were in Florida. I had sent it in the mail and they didn't get it until after they got back. So she GAVE IT TO HER FRIEND! Now, tell me if I am crazy, but that card is associated with my credit card. I felt comfortable with her having it, but now, it's just out there. Should I be worried?
