How do people normally pay for groceries? If I asked you that question several years ago you would have said that people pay for groceries with cash. Have things changed? How are people paying for groceries today? According to reliable sources it seems that people are buying just about everything with a credit card. In Portugal credit cards are known as Cartoes De Credito.
Credit cards can be very useful, but one must understand all of the terms and conditions associated with the use of such a card. Along with the privilege of having and using a credit card comes the responsibility of using it intelligently. Because it is so easy to use a credit card, some people get into trouble by purchasing more than they can actually afford. Not unlike actual money, credit has to be managed. One should not buy more than they can afford.
Having a credit card allows one to take advantage of opportunities that might otherwise slip away. Just remember to use it wisely.
