Pre-order or Pre-purchase
I am/was very interested in this book, but understood it was a pre-order, not a pre-purchase. I pre-ordered it when it was first announced, but just noticed on my credit card bill that I have already been charged for it, as of March 17th, which is 6 to 10 weeks from the actual release date (assuming it does indeed come out in May).
How come I have already been billed for the book? Was this an error?
