OMG - I'd be hyperventilating! Mine was same day service using a credit card, and I did it a month in advance because a) I'm anal that way and b) I'd be spending my time breathing into a paperback otherwise!
That $50 is well spent. I easily read over $50 a month worth of books! Much better selection than my MD Overdrive (usually) has.
Hope they get back to you soon!
