I used to get offers in all the textbooks I bought when I was in college. Plus, the college had flyers up on every bulletin board.
I never wanted to get one, but my Dad saw the offer one time when it fell out of a book and I hadn't thrown it away, and made me apply for one. He told me to put a tank of gas, or a lunch on it once a month and pay it off in full. He said it would build up my credit. It sure did, and I recommend it to everyone.
FWIW, my wife always paid cash or check for everything when she was in college and since she lived at home when she went to college, had no bills. Because of that, she had no credit when we were first married and had to get a secured card from her bank just to build up credit.
