Macbook Pro 13" Unibody with 7 months of warranty in Jurong West Street 81, West Singapore for sale

I'm selling away my Macbook Pro 13" Unibody with more than half a year of warranty left (7 months, until 29/12/2012).
Details specs:
+ 2.53 GHz Intel Core 2 Duo
+ 4 GB 1067 MHz DDR3
+ 500 GB HDD (Upgraded)
+ NVIDIA GeForce 9400M 256 MB
+ Backlit keyboard
+ Currently on MacOS Lion (Recovery disc is Mac Snow Leopard)
Package include:
+ Full box with all original accessories
+ Proof of warranty (until 29 December 2012)
+ Free gift: Apple Mighty Mouse
Item is in very good working condition (anyway, it's still covered under warranty), there're some unavoidable scratches, but other than that, everything looks fine. Battery life still as new, last for more than 6-7 hours even with Wifi on.
Price is fixed at $850 (selling at a huge loss), so please don't ask for my best price or best offer, I won't respond to these sms.
