New addition to my addiction

Strange things are happening at the Book Depository. This book was dispatched on December 24, and it was delivered yesterday evening, by a very wet mailman, and I had to sign for it!
One: why does it take over 3 weeks to reach me?
Two: since when do I have to sign for those books? I'm never home during the day! They just push it through the mailslot in my door!

Okay, the book is:
Deep kiss of winter by Kresley Cole and Gena Showalter.
