### Shipping Calculation

Hi Folks,

Can you help point me in the right direction with some shipping rules?

I need to create a shipping rule for Postage A = \$1 and any additional products that use Postage A = \$0.

Postage B = \$1.50 and any additional products that use Postage B = \$0.50

Postage rates are held in a database and the column name for Postage A, B etc is PostageName.
The Postage Rate is held in a column name PostageRate.

So i would be calling the Name (A,B etc) from PostageName, The rate for 1 product from PostageRate and the additional rate for any product over quantity of 1 from PostageRateAdditional

Cheers.

so this postage rate table is a separate table from the products table? is that correct? or is the postage rate columns a part of the product table?

I need a little more detail on the way this is set up.

Hi Jason,

This is held in a separate table.
The product will reference the postage table via a flag.

Cheers

The product will reference the postage table via a flag.

please clarify what you mean by this.

The product table has a field in it for Postage A,B,C, D etc and this references the corresponding field in the postage table to match off via a join.

So if a product has a postage rate of A then via the postage table this will produce a postage rate of \$1
If anything else in postage rate A is ordered it will add no charge

If a product has a postage rate of B then via the postage table this will produce a postage rate of \$1.50
If anything else in postage rate B is ordered it will add \$0.50 per item after the initial \$1.50

etc

Postage rates are held in a database table and the column name for Postage A, B etc is PostageName.
The Postage Rate is held in a column name PostageRate.

So i would be calling the Name (A,B etc) from PostageName, The rate for 1 product from PostageRate and the additional rate for any product over quantity of 1 from PostageRateAdditional

Ok, the recordset used by the add to cart button should use a join query to return the associated shipping rates.

in your cart object, create a column for baseShipping and another column for incrementalShipping.

in the add to cart button behavior, bind the baseShipping column to the PostageRate column in the products recordset, and bind the incrementalShipping column of the cart object to the PostageRateAdditional column from the products recordset.

on the calculations tab of the cart object, create a calculation as:
itemShipping
[baseShipping] + (abs([Quantity] > 1)?([Quantity]-1) * [incrementalShipping]:0)

then on the shipping tab, create a shipping rule to use the itemShipping calculation.

Set the trigger to:
Subtotal for any column:
if the column "itemShipping" is ">" a value of "0"

for the calculation, use:
Based on multiple of column subtotal:
Subtotal of column "itemShipping" "times" "1" "plus" "0"
