If you have or use a credit card, which one or how many do you have?

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 4 credit cards (yikes!) - Citibank Visa Clear card - Citibank MasterCard Clear card (don't use this at all, might as well terminate it *note to self*) - Citibank Visa Gold card - HSBC Visa Classic card :D

I use only one debit card =VisaElectron. There are small amounts there. I use it for bank transfers from my e-gold.

I have no credit card, but now I want apply for it.
