Credit Cards have played a definite role in increasing the monthly spend of people. It sounds so good with presumable 0% finance; incentive points on shopping; and no money changing hands that you end up with feeling of getting every thing virtually for free.
If used sensibly, credit cards are a very useful tool for modern day life, but these Credit Cards are double-edged sword too. No doubt that they do help you improve your living standards, allow you the comfort of carrying minimum cash; but these cards need to be used responsibly, else you can become an out-of-control impulsive buyer.
