i wouldn't preorder anything from overstock.
I preordered Radiata Stories for $29.95. The ship day came and went. It took me at least a month to make them refund my money. When I called they said the game shipped, even though it still said processing. Then they wouldn't refund my money, so I had to get a trace on a package that never shipped... then two weeks after that I finally got my money back. In the mean time I bought the game for $34.99 at BB with GCC.
So all in all... don't expect this game to ship on the release date. If it does ship, expect to get it at least two weeks after the date.
Best Buy usually does $10 off Square games either the first or second week they are out.
Sorry for the long post, but overstock sucks for preorders IMO
