As an interesting side-note...I had resolved to cancel my Amazon order and get it from Buy.com, as some other people here had done. They offer it for the same discounted price.
BUT
Buy.com is sold out of the gift set, as of about an hour ago.
I guess it's fair to say that sales of the new books have been, um...good?
Getting them individually from Amazon comes to 62.91...about $5 more than you'd get for the boxed set. And they're available to ship immediately. Buy.com seems to only have the PHB individually, not the MM and DMG. The boxed set is the #1 seller in books, today...
Barnes and Noble.com has it for $75-ish, discounted to 66.11 for "members". The individual books are available for 22.01, but the Gift Set and the PHB are listed as "usually ships in 1 or 2 days", so beware of back-orders there, too.
Borders Online has the individual books for the same amount as Amazon, but no gift set, and the MM is back-ordered.
Even getting them individually, Amazon is still the best deal out there, among the major retailers. If only I wasn't miffed at their blow-off response to my e-mail, and too stubborn to bite the bullet and send them any money...
Anyone else know of any good deals to be had?
