I bought my black and white flyknits in a store this August for $150 plus tax. Recently sold them because I realized I needed a real running shoe (bought Air Pegasus). The flyknits were used with some noticeable wear, so I started an ebay auction at $0.99. Someone offered $100, then $110 if I cancelled the auction. Was really tempted since I wasn't expecting that much but I decided to let the auction go. They ended up selling for $158 + $12 shipping. That was a nice surprise.
