The £300 ones im talking about are damaged but I was more going by what the prices on ebay sold were. I also know the person selling it so its not had really any hard use and hes only upgraded as the MacBook doesn't fit in his prada day bag LOLLLL. So hes went and got a top 13"
I may be far off the mark but 900 is a bargain IMO.
No way any have sold for £300, or if they have its fluke.
