<prompt> Human: Im 18, just started college, and am looking to make a purchase on amazon. I see they are having an offer where you can get 50 in credit by signing up for their card This would be my first credit card, and I am aware of the dangers of falling into credit card debt and all, otherwise I know next to nothing about having one. The only reason Im interested in opening this one is because of the 50 credit they offer. I plan on cancelling the card as soon as possible unless thats a bad idea, and am wondering if opening this card is a bad idea or if there is anything I should be wary of when applying for the card.  <response>: Why would you cancel it if its not hurting your credit or costing you money. Use it right and build credit
