If you are unmarried and/or have no children to support then you don't need credit cards. But if you live in USA you will eventually join in the Great American Dream and get up to your eyeballs in debt. Almost nobody lives in this country debt-free and credit-card-free.

I got 4, 5 if my debit card counts(works like a credit, minus the "debt" part).

2 cards with no balance, 1 card with some balance that I don't use, just a matter of paying it off. And the 4th is a work credit card that I only use when I travel for work.

I'm pretty good with my credit cards. Ran them up a bit during college to survive. Rarely use them now. I use my debit card, that way I know when I buy something I already have the money for it.

Same here..

Just one, which I use mainly for online purchases and gas (which is reimbursed by my employer at the end of the month, so why pay for it in advance ).

For online purchases, a CC is almost a requirement. PayPal is unreliable (they're fraudsters), IMOs are slow and reek of fraud as there's no safety built into the transaction, and international bank transfers are slow and expensive (and hardly any online store will deal with them).

I think an interesting corollary to this question might be, "How much credit do you have (supposedly) at your disposal?" There are several piles of plastic I have no intention of ever using lying around, for example.

I just have the one which I got a few months ago. I don't really use it much and I guess it's there just incase I need it ... and cocaine of course. How else can I break it up?

I am strictly a cash person! Credit cards are evil, an easy way to trap stupid people!

Meh. You don't have to be not-stupid to keep yourself out of debt.

Im 17. I dont have any credit cards, but i have a debit card (need for college etc...). Debit is better IMHO as you cant get in a huge amount of debt and there is no interest and it goes right to your bank account
