Forever 21 NYC or Forever 21 online?

Okay so Forever 21 is my all time favorite clothes store. And soon I'm gonna go back to school shopping and I was wondering if you think I should go to the Forever 21 store in NYC Times Square which is the biggest F21 in the world.... 4 floors.... I was their about a year ago and it was great. Or should I just buy stuff online from Forever21.com? HMMMM
