The thing about finding a credit card to use as a tool to start building your credit profile is that there are several important features you are going to want that card to have. First of all, you need to make sure that whatever card you apply for, it will report your credit activity to major credit bureaus. This is what actually allows you to build your credit profile. The next thing you want to look out for is that you do not earn an unpayable debt on your first card. Missed or late payments look bad, and they can leave you with an even worse credit score. We would recommend that you apply for whatever card you think is best. When you have the card make sure your Aeropostale online purchases are reasonable enough so you can pay off your bill on time.
