Do you use Credit Card?

I use my credit card hevaily and will use it whenever the outlet accept it. I have 5 credit cards and I only actively use 2 out of the 5 cards. The reason for me to use the 2 active cards is that they are co branded card and I will be given discount when I use the card to buy their products. One of the co branded card is with a petrol company and it help me to save up to 10%, and the other one is with an airline, it help me to accumulate mileages for air ticket. The other 3 cards are more for standby, just in case my credit limit is max out, I can use it when I really need it.

I have always been tempted of getting a credit card since I started working. But my parents and my boyfriend always give me their cold shoulders every time I open up that topic. They know credit cards are helpful somehow, but they are very firm in laying down to me the disadvantages of getting one, especially if I would be very indulged in it. And besides, I've seen the dilemma of my colleague before who happened to have a credit card bill summed up to some Php 45,000 or roughly US$ 958 for just a month... :( She did have bad headaches on how to get all those bills settled, and add to that her husband who was in the very first place against her getting a credit card... huhuhu :(
