It can be exciting to see that credit cards will give you cash, or other rewards, just because you spend money.
However, it’s important to realize that not all credit card reward programs are worth the trouble. Indeed, some of them have such difficult redemption policies, and there might be other costs, that significantly reduce the value of your rewards.
Before you start spending like crazy, consider the value of the rewards, and whether or not they will really work for you.
And consider some of your habits. You could be following financial practices that reduce the value in your credit cards, and not even realize it.
