How important is it to maintain a good credit score?
Having a credit card doesn't mean you can just do all the shopping and just swipe your credit card to pay everything. If you have a credit card you need to maintain a good credit score. This is through paying your credit bills on time and as much a possible don't maxed out your credit card.
For me it is very important to maintain our good credit scores because having a good credit history also means you have a good reputation financially. Having a great credit score would also give you privilege to be able to loan for a house or a car.
Aside from paying your credit card bills on time and not over spending, it would also help if you get a credit report every month so that you will know no one has stolen your identity. Check the site freescore.com for more info.
