Don't like the fact that your friend just signed up for the same credit card as you but she got a $50 bonus because she used Tiffany's sign up code? Look we don't like Tiffany either but that is no reason to miss out on $50. Search for any kind of refer a friend deal like a credit card referral code, or cable referral code, or whatever referral code here before you sign up. That way you get $50 and Tiffany doesn't get jack.
