<prompt> Human: So I just got approved for Amazon store card by synchobank? for 800 dollars. Before this, I have applied for discover, chase, and chase amazon but all were declined but finally I am happy to get Amazon store card. I never had credit card before, and this will be my first credit card, and I need help advice on best way to build credit. What would be my first step? Also is this only available for Amazon purchase only? or can I just it anywhere  <response>: Pay the statement balance in full on time every month. Dont buy anything with it that you cant pay for with cash. Thats it.
