Buying baby items before pregnancy

He
I have been TTC for 8 months. I go in spurts but I love to shop for and buy baby items like clothes, books, a few decorations and organization for the future nursery. It mainly helps me to feel like I am making progress toward my goal. I don't plan to have a baby shower and am buying things that are great deals like clothing at a consignment shop (hello 60cent onesies in great shape)! I'm also not superstitious that this will affect me or jinx me as others say. 
Does anyone else feel this way and shop without being pregnant yet?
