Hi I am new to Zen Cart. I have an issue concerning shipping modules. My company is currently using the yahoo store. We have decided to do it ourselves using Zen Cart. Everything so far is working great. My companies wants to retain the way we are current shipping through yahoo. However I am not sure how to get Zen Cart to do it.

The issue is:

The shipping charges are a rate per order + a rate per pound (example: $10.00 per order + $3.00 per pound).

I see a shipping module for flat rate and one for per weight, but nothing to allow me to apply both.

any suggestion?
