subtract weight or tare per item in cart

[mental.piracy]

is there a way i can change some script to tell zen cart to multiply the tare or negative tare rather, by how many items are in the shopping cart?

[mental.piracy]

per additional item after the first item,
like 1.5 lbs per item after first.

Using the Developers Tool Kit ... do a search on:
SHIPPING_BOX_WEIGHT

This will show you all of the files where the Tare is addressed and you can customize that the way you need it ...

can anyone give me any idea of the code format i would use for taking off 1.5 lbs per each additional item in shopping cart after the first item?

[mental.piracy]

maybe multiplying the tare by -1.5?

In the shipping.php class the Tare is handled:

      switch (true) {
        // large box add padding
        case(SHIPPING_MAX_WEIGHT <= $shipping_weight):
          $shipping_weight = $shipping_weight + ($shipping_weight*($zc_large_percent/100)) + $zc_large_weight;
          break;
        default:
        // add tare weight < large
          $shipping_weight = $shipping_weight + ($shipping_weight*($zc_tare_percent/100)) + $zc_tare_weight;
          break;
      }

you need to adjust the formula for how the $shipping_weight is managed based on the Tare ...

well, i'm retarded, all I had to do was set the product weight to 1.5 lbs less, and put in a positive tare weight of 1.5 lbs; I swear I tried that before and it didn't work, oh well, I only lost 3 days worth of work. Se la vi.
