Was just browsing on the Dell site and came across this offer. Dell ebay sell it at the same price, but you can use the Ebay Cashrewards for further 2.5%. Good price for this unit.
Cashrewards have 5% cashback from Dell. (I have never bought from Dell direct using Cashrewards, I am unsure of this part)
They also have some codes on their site for additional 5% off for the Dell store, but if you use the codes, it nullifies the $400 discount already applied.
They also have the i7 on sale.
Note: this has a 1080p screen
awesome, but i can't buy as i have to sell my existing laptop before buying this :(
