I am using USPS priority mail as my shipping method. My problem is:
everything needs to be sent with delivery confirmation which adds another $.60 to the price, and...
higher cost items need to be insured.

how to add these costs? I could just add the del. confirm into the handling cost, but then it says handling charge, which I do NOT charge....

I have my usps api account running, I'm using ZC v. 1.3.8
thanks
