Now that i am upgrading to rMBP, planning to sell my 2009 MBP 13" to cover rMBP expenses. just wondering what's the best way to sell and get best price. I am not even sure how to price. Here is the my 2009 MBP 13" spec: Original config: 2.26GHz Intel Core 2 Duo/4GB/250 GB recently (May'2012) upgraded memory and storage with following config - Memory - 8GB (crucial) Storage - Seagate Momentus XT (with 4GB SSD cache) (Model: STAN500100) Will update to Mountain Lion OS. MBP is in very excellent state, no scratches. Planning to include original 4GB DIMMs, 250GB HDD, & incase sleeve as free goodies. Appreciate any feedback.
