I'm not looking at this at all because I'm working overtime from another PC, but I wonder if perhaps changing the sort order of the order total modules will resolve this.. In other words I wonder if moving the shipping insurance's sort order above the gift certificate's sort order that it will apply the gift certificate to the shipping insurance.. (I think this is what I understand it is you want to have happen)

When I pay for my test order in full with a gift certificate, the shipping insurance is not deducted from the gift certificate amount, and a balance for the insurance is ending up showing owed in the total.

Example: Subtotal is 14.95. No Sales Tax. Shipping Insurance is 1.40. I have a gift certificate balance of 25.00. In the Gift Certificate area of the check out, I apply 16.35 of my Gift Certificate Account balance to the order. I click "Continue Checkout". The OT balance on the next page should be zero, but it's 1.40 - the amount of the shipping insurance.

I'm having this same issue with Priority Handling Fee - but that's another mod that unfortunately doesn't seem to have a support thread.

For whatever reason, the fees from neither of these mods can be paid for with a Gift Certificate, and coupons deduct from them separately from the OT.

Any suggestions are appreciated.
