BOOK PRE-ORDER UPDATE: Someone told me that they had received an email from Storenvy asking whether they'd gotten their order yet! This is probably because I have the shop closed/disabled and because of the wait. Oh dear.
The books are definitely on the way!! The order status says it's in queue for printing, and my original ship date estimate was the 14th, so I should have them by sometime next week :)!
Also, today is my 24th birthday! Whoohoo!
