When am I going to get my freaking free poster from Teen Vogue?

I registered on the teen vogue website because it said that if you registered then that you could get a free poster of Emma Watson. But I can't figure out how to double check that I'm going to get it or anything like that. Does anyone know how to make sure that I'm going to get my free poster or when I'm going to get it? I mean, do they send a confirmation or do they just sent it to you and it'll arrive in the post randomly some day. Anyone know?
