Use this module to generate shipping charges based on the number of items in the customer's basket.
Quantity based shipping has two modes: standard and progressive. In both modes you create a set of ranges for the number of items in the customer's basket, and each range has a shipping charge. For example:
Range 1: 1 - 3 items, charge $3.00 shipping per item.
Range 2: 4 - 6 items, charge $2.00 shipping per item.
Range 3: 7 - 10 items, charge $1.00 shipping per item.
In standard mode, the software looks at the total number of items in the customer's basket, figures out what range it is in, and charges that amount for every item in the basket. For example, using the ranges above, if you had 5 items in your basket, the shipping charge in standard mode would be:
5 items falls into "range 2", so we'll charge $2.00 shipping for every item in the basket.
5 items x $2.00 shipping each = $10.00 total shipping.
In progressive mode, the software looks at the total number of items in the customer's basket and applies the shipping charges from one or more ranges. If you had 5 items in your basket, the shipping charge in progressive mode would be:
The first 3 items fall into "range 1": $3.00 per item x 3 items = $9.00
Items 4 and 5 fall into "range 2": $2.00 per item x 2 items = $4.00
The total shipping is $9.00 + $4.00 = $13.00.
