Use it to build your credit! Make small purchases with it regularly, and then pay those purchases off in full every month to avoid paying interest. Don't max out the card — in fact, strive to keep your balance below 30% of your limit. Ideally, you won't have this card forever. It's a tool you use to demonstrate to lenders that you can handle credit responsibly. As you build a solid payment history and your credit improves, you can start looking at cards with better benefits.
