It's also worth noting the difference between the credit card systems in the Europe, the US and many others.

The US and a lot of other countries have a credit card system that allows you to conitnue spending to your limit as soon as you reduce the level of debt (ie. pay some off), or increase the amount of debt they can take on.

In Europe, even if you were to pay some of your credit card off you cannot continue to then spend to the limit again in that month.
