The store I'm working on uses the UPS and USPS shipping modules. The problem is that we need to set it up with a minimum shipping fee of $7.95. For example, if the quote for USPS Priority Mail comes back as $4.95, a $3.00 charge will automatically be added.

I was hoping that there would be an add-on that would accomplish this, but I appear to be out of luck there. I searched the forum for a solution, but struck out here as well.

Does anyone have a suggestion on how this could be accomplished?

The store uses ZC version 1.3.8.
