Amazon.com now says it has Windows Vista Inside Out, Deluxe Edition, in stock and available for immediate delivery. I still haven’t got my first copy, but that’s not unusual.
If you preordered, you saved five bucks percent [corrected, courtesy of pocketdragon in the comments]. If not, the current price is still a good deal.

Actually, according to Amazon I saved an additional 5% (1.89), not 5 bucks, for my pre-order.
I just received notice that my copy has been shipped. Now I’m waiting for the pony express to deliver it.
