I'd say print out the spec you want and give them a call. The sales people in India all want your money and you can usually get things like accidental damage and extra warranty thrown in for free as long as you have the cheek to keep asking for more. Don't ask for money off until you're sure they won't throw anything else in.
Seriously, I have never seen a web offer with Dell that I couldn't get at a cheaper price over the phone. I saved my brother about £300 (+ extra warranty and accidental damage insurance) on his laptop and I got a free USB tape drive thrown in for free on the last laptop I negotiated for a friend. If the first sales person won't play ball, call again and try someone else.
There's always one sales rep who will go a bit lower than the last
