I've got mixed feelings about this.

To me the ideal scenario is the one that Porcupine describes, building up the protection of some savings to cope in most difficult situations.

Of course the savings might not be enough to cover every scenario, and not everyone will be in a position to build up a decent level of savings.

However we're all well aware that credit (and access to credit) doesn't come without risks. I can imagine that plenty of readers of this forum will never want to go near it again.

I think having a credit card can be very useful sometimes. I often use mine if I am making a larger purchase as it gives an extra level of protection if there is a problem with the goods being unsatisfactory or not delivered. As I understand it, the funds can then be reclaimed through your credit card provider under section 75. I must admit I don't know all the ins and outs of this, but it's something you often hear the ubiquitous Mr Lewis talking about.

Ideally of course, you have the cash saved too and then pay off the credit card balance straightaway.
