Hi I have just got me credit card to ZERO!! And, that's how it's going to stay ,hopefully.
If something is worth paying for then it's worth saving for. But if you want it now and are prepared to pay interest then use the card but pay it off A S A P.
Do not use the card to supplement/support your lifestyle IE meals out, fuel, car tax etc etc. Use the card as a simple way of spending money that you have not what you might have in the future. Credit cards are Brilliant but only if you pay them off each month
