O.o Amazon is scary

I placed an order at amazon, maybe 15 mins ago, at most. I ordered my dad's x-mas gift and a manga for myself to meet the minimum order value for free shipping. It's Saturday evening. I had just sent the order off when I saw on the recommendation page a manga I've been looking for all week and hadn't found when looking on their page. They had never carried this publisher before! So I thought "Yay! Let's cancel that order and get this manga instead!" So I tried logging in, but it failed at first. I went the long way, finally saw my account, clicked my order... and mew? Apparently my order already has been dispatched! Meep! I must have my own private dispatcher or something! *giggles* I already knew I'm a pretty good customer, but this is kinda surprising...
