The Old Mutual Investment Credit Card Account is a dual card product. The reason for this is that, should you experience problems with either credit card, then the other is there to serve as a back-up. So, for example, should your Old Mutual American Express Investment Credit Card not be accepted by a particular retailer, your Old Mutual Visa Investment Credit Card can be used instead. This way, you are always able to pay while earning a percentage that will be invested in your money market unit trust. In addition you can double (at least) your investment rewards by using your Old Mutual American Express Investment Credit Card at our retail partners.
