It's still got 4 days to go, the price will go up making it less and less of a bargain.
Also if you are not getting the owners manual are you getting the warranty card?
With all the problems people have reported here with their new s 900's I would only buy from a dealer I could trust to stand by me if there is a problem. It wold be worth any extra money for the peace of mind.
IMHO Lets watch it for a while.
