I owned five credit cards in my wallet and I only used the two of them. A credit card for me has pros and cons. In a way, it is very much helpful in an emergency case like buying milk and diapers for my baby and booking online tickets. But I guess the disadvantage is that if you are an impulse buyer like me, you will end having problems at the end. LOL! I am planning to use the other credit card since I wanted to avail the balance transfer since it has a lower interest rate. I am pretty sure that it would be much okay since it has so many advantages. I guess I really have to use it wisely!
