Just trying to share some experience here since I used to do retail pricing analytics. The $15 prices will come back, if not lower (though perhaps through alternate offline discount-store channels).

If you look at how the price continues to fall after October through Christmas shopping season by one inventory holder (1saleaday, probably has 10k+ pieces to liquidate) and how poorly the deal has been moving even with guerilla marketing (see: views on each thread, as well as thumbs-up)... all I'm saying is that this deal's been a dog in retail.
