The type of credit card that you should use to complete the purchases is going to be based on why you are choosing to use a credit card to complete your purchase. If you are using a credit card because you don’t have all the funds together, you may want to consider applying for a card with a 0% introductory APR or a low fixed APR. By using a card like this to complete the purchase, you can avoid getting stuck with high interest fees. If you’re only choosing to use a credit card because it’s an online purchase, you may want to consider using a general rewards credit card to collect a large sum of points from the purchase. As long as you don’t plan on carrying a balance, a general rewards credit card is the probably the best option.
