Shipping Coupon Discount is calculated with Taxes

[butterscotch]

Hello All,

Wondering if someone can help

I have setup a Free Shipping coupon for orders over 600.

1) When the coupon is accepted the final screen does not show the discount for the new coupon. Is there a way to fix this?

2) I would like for the shipping coupon to behave slightly differently - any hints?
