Ok...you are right...and thank you for helping me think this through. I believe what I need is the ability to set a price and have the shipping calculated by weight, postcode ( zip code in US ) origine and destination, and country. So I would set a price code of for example $10 and based on the product weight, the warehouse zip code and the shipper's destination address zip code the amount would be calculated. Does this sound correct? See the attached screen shot from the VM shipper plugin. Do you have anything like this already? Minimally, I'd like to show "0.00" rather than "Free" and the message "Shipping will be billed on invoice".
