You can talk to the Dell sales rep online and can haggle for the price, I was able to negotiate around 150-200 sgd off...
There is also a Game Pro shop in Funan where you can check AW, I believe their prices are fixed but they will give you some freebies.
I didnt really need the freebies and the spec I was looking for was not available yet at Game Pro so I went to buy direct from Dell.
