My order 400012055 || Ordered Sept 15th says "Pre-shipping, Backorder"What exactly does that mean? It also says that one (out of three) of my items has shipped, but not the other two. So, just a little confused is all.Trying to get it before Oct 4th, which is my friend's birthday. So hoping I'll get it by then. Once it says shipped, about how long will it take to get to me? Thanks for answering.<3
