There’s a school of thought that says buying things on credit isn’t the best idea. However, that’s mostly a very old school of thought! Your grandfather probably told your dad that, and his grandfather told it to him. The truth is, credit cards are a fantastic financial tool. For example, if you’re buying something sparkly at K Jewelers, you can actually get rewarded for spending all that money. When you use a credit card, you can get cash back, frequent flyer miles, points, and more. You also may get purchase protection, price guarantees, and other perks, depending on the specific benefits that your particular credit card offers. As long as you pay off your purchase within the agreed-upon time and according to the terms and conditions of your card, using a credit card is a great idea, and one that you could probably even win your dad over to.
