How am I supposed to get signed Taylor Swift CD/Vinyl?!?!

I have been trying to get one of the Life of a Showgirl CD signed and have not had any success. Honestly don’t think I will because for the last drop at 11:30 I had two in my cart by 11:31 and they still sold out before I could buy them. Don’t think I could have gone any faster!! Does anyone have any tips??
