Hi!

I am trying to figure out which FedEx mod to use. I have a ZC 139d site.

I ship both large and small products (850 lbs surgery table or a 1 lbs light bulb). So I need both ground and freight.

Here are the two FedEx mods I have found:
FEDEX
FEDEX XML

Because I primarily drop ship, I really need this mod:
Origin Based Drop-Shipping (requires FedEx module)

It appears I will need the FEDEX mod, not the FEDEX XML mod. But can someone explain the difference? I wonder why there are two mods that appear to do the same thing?

Thanks,
Mike
