Query: Never Pre-Order with Amazon

I have had dreadful experience with Pre-Orders here at Amazon.In this instance, my order now reads "projected shipping date 21 September". are you kidding me? This DVD was released on 15 September and I PRE-ORDERED it. One day I will learn my lesson. I also pre-ordered Star Trek. I'm cancelling that one. I'm better off driving over to Walmart to buy my new DVD's.
