Ideally it would take all the products shipping from one location and get a shipping price from UPS then take all the items shipping from another location and get the price from UPS, then present the total shipping cost to the customer. This would require a FOB location to be specified in the product listing in the store for each item. Setting a default FOB location and changing it for items that vary from the norm could make entering products easier.

I've been looking for a contribution that would do this my self. I ship a number of products from in house, and ship a good bit by drop ship as well. The double shipping kills me sometimes. A way of getting proper shipping costs on orders that ship from more than one location would be great. Unfortunately, I read Greek better than I read PHP or I'd write it my self. :) This is something that I and I'd imagine a lot of other people could really use.

If there's any way that a non coder like my self can help, let me know. I'll do what I can.
