They are/were being sold by a dealership in Toms River, NJ. I'm guessing they just ran out of stock.

I paid $199.98 plus tax for both sets, same as I would pay at the dealer. I don't expect that price to change up or down for at least 9 months to a year. Maybe not even then. They're new so nobody knows how popular they will be. If they're popular, the price will eventually go up. If dealers can't get rid of them, the price will go down. Eventually.
