This is very true.
Having many credit card is not a bad idea when you do not need a BIG credit purchase, but before that. Some bank will issue you a interest rate based on your credit score.
Nowaday, regular credit card is outofdated. A reward card will be the trend. Like citibank's driver's edge. American Express's Airmiles....CIBC Aeroplan. Why not get reward when you use it~
Personally recommend 2 cards with 3000 limits would be ideal. Credit card sometimes serve as emergency cash and if its too low. Sometimes cannot help
