The UPS version seems to be working well so I decided to apply the same logic to USPS Shipping to allow for multiple boxes. As a plus it can estimate if a small, medium or large flat rate box will work for the order (though it won't include a flat rate box when shipping multiple boxes unless all boxes are the same flat rate size).
This is an enhanced version of the standard usps shipping extension. It allows for shipments over 70lbs and uses product sizes to determine box sizes. It does not use a packing algorithm, but uses a more simplistic volume calculation. It's not ideal, but is much better than having no size associated with shipments.
Features:
- Minimum and maximum shipping weights.
- Minimum and maximum volume (box size).
- Minimum shipping rate.
- Weight and volume adjustments to account for shipping box and packaging (fixed and percentage).
- Rate adjustment (fixed and percentage).
- Disables flat rate boxes if the calculated box is too large.
To Install: There are no modifications to existing files. Just copy the files in and setup the shipping method.
Notes:
- Only the gross shipping weight is displayed, not the dimensional weight.
- The box size calculation is very simplistic. It calculates the total volume then assumes an approximately square box. However, it will not make any dimension of the box shorter than longest corresponding item dimension.
- Make sure you test it's function first when using flat rate boxes since the selection of flat rate boxes is dependent on the box size calculation.
- See the 'UPS Shipping - Alternate' extension for the UPS equivalent.

this mod seems to be working fine, i just don't exactly understand how it works.
For example, I have an item that I know fits in a flat rate small sized box. The weight is set to .5lbs and the dimensions are 1x1x1. How come when I test it out the flate rate small sized box does not show up? Only the medium or large.
Any help would be greatly appreciated.
