Credit Card Question 0% APR for 6 months

[pmuir10]

if i get a credit card that has 0% APR for the first 6 months and make a bunch of purchases on it for a month or two, but i dont pay those off until say the 5th month, i wont have to pay any interest on them right?

does doing something like this hurt my credit score though? i figured it might not since im not paying any interest on my purchases even if im paying them late..

about me: im 20, in college and in a bind for cash thanks to paying taxes on my poker winnings recently.. dont think i even have a credit score ATM..
