I have been thinking about switching from my early 2009 iMac to a Macbook Pro for a while now and had been planning to wait for the 2012 models, but lately I've been seeing quite a few used 15" 2011 (early and late) Macbook Pros for sale. My question is what would be a reasonable discount at this time? I saw one guy who was selling a top of the line late 2011 Macbook Pro for almost a third off
. I naturally sent him an an email saying I'd take it, but assuming I don't get it, what would be reasonable? 10% 20%?
