Hello,

I'd like to make USPS insurance an option for the customers on my site.

Here are two concerns:

1. I get a big discount on USPS insurance from my current shipping software provider. Can I pass the insurance savings onto my customers? I don't want them to pay more than they need to.

2. USPS Priority flat rate already comes with $50 of free insurance. I want Zen Cart to know that insurance purchased for Priority flat rate will be additional insurance. Will this pose a problem?

Thanks in advance!
