From the US mint site:
"The United States Mint will implement an order fulfillment charge of $12.50 for each box of $1 Coins purchased through the $1 Coin Direct Ship Program effective November 15. This new charge is a result of our continual effort to review programs to ensure that they meet our commitment to prudent fiscal management on behalf of the American public."
That's unfortunate. I like the dollar coins but I'm not willing to spend money to use them, and imagine a lot of others will feel the same way.
