I have been watching retina, 15' MBP lately on ebay. I add things to my watch list to keep a track of what they are selling for before I'll buy one somewhere around July or August. A listing had a late 2013, retina 15' MBP, that was maxed out. Battery cycle is under 50, ships with original box and everything. I was communicating with the seller about a buy it now price, and we had a deal for about 2000, which I later stopped responding to as I realized I value Applecare way more than a 1TB SSD and a top of the line graphics card. The listing sold for more than 2,500. However, the seller informed me that the buyer was 'no longer interested'. Why the hell did he keep bidding and then decided 'no'? As for the seller, he has more than 100 reputation points (100%). He has told me that it is in excellent condition (basically new like he told me) with no scratches or dents. Does something seem fishy? Oh and it does come with more than 6 months left of apple's 1 year warranty.
