Any advice for getting a kid off to college?

I am getting my 17 yr ready for college and it's been a real chore. She would rather run around with her friends then get to the stores and get the things she needs. This battle has been really worrysome for me, so I am counting the days till I drop her off. What ever she does not have, she does not need. I will not be pulled into last minute drama, I mean it, I chant it like a mantra!
