Cash, always cash(unless online of course). I only decided to get a credit card because a website wouldn't accept my debit card, the only other thing I used it for was paying for my driving practical and theory test.
Did anyone else when applying for a credit card get asked how they would pay off the debt if you lost you're job? I had no idea what they wanted me to say to that, I mean it would be impossible.
The only questions I answered were name, address, and phone number and what credit limit I wanted.
