Shipping Options Dependent on Cart Total

Hello All!

I have a shipping issue I hope somebody can shed some light on.

I have a shipping promotion that offers free standard shipping for US orders under $199.00.

I had to create a shipping method called “Free Standard Shipping” and have that set as the bonus for the promotion. The promotion is given and taken away as it should based on the cart total.

The problem is that the “Free Standard Shipping” option still remains available during checkout.

Is there anyway to only have that shipping option displayed if the cart total is under $199.00?

If not, how else can I accomplish this?

Thanks for any and all help.
