There was a shortage previously which is no longer the case, maybe they just forgot to update the prices or hoping there would a shortage in future i guess.
I have one I'm willing to sell. They're $450 in the store. Willing to take $275 and buyer pays for shipping via ups or fed ex. (For tracking purposes) only used once about 3 months ago. Selling because my model s is sold.
