Quoting Ron Phipps (rphipps at reliant-solutions.com):
> Has anyone built shipping tags that work in a multi box situation?
> Here's the deal. A client ships parts each weighing an ounce to 100lbs.
> I have identified the following scenarios:
> 1. Total weight is less than max weight for shipmode
> 2. Total weight is more than max weight for shipmode, but each item
> alone does not weight more than the max weight
> 3. Total weight is more than max weight for shipmode, but 1 or more
> items along in the order weight more then max weight
> Scenario 1 is easy, you price it like IC does now based on total weight
> of the order
> Scenario 2 is more difficult because you need to figure out how many
> boxes (not taking into account dimensions) and the weight of each box.
> You want to fill the first box to as close as max weight as possible,
> then the second box would be the left overs (or there could be 3 boxes,
> 2 being as close to full as possible and the 3rd being the leftovers).
> In this situation it's almost as though you need to arrange the parts

I did a Vend::OptimalPack box-packer once for a beverage company. It had
to fit 12-oz and liter bottles in different boxes, etc. You have to have
a database of what each box-type is, what items fit in, etc.
I handled it by making each box an SKU and doing a transparent order
into the shopping cart. (That is where the mv_transparent_item part
of IC came from.) That takes care of adding the weight to the order.
I don't think we have the old archives searchable anymore -- I think
that module might be lost now. But it wouldn't be too hard to
recreate if you put your mind to it.
