Extra product shipping charge problem

[Steven Barkess]

Hello

So, I am charging 2 gbp for my first product and 0.60 gbp for each additional product.

I have set default weight to 0.75, and the respective price in the table as 2 gbp, and also Increment highest value by 0.60 gbp per 1.

This almost works but... below is a table of prices that customers should pay, and the amount actinic is charging:

Qty Correct Price Actinic charge
1 2.00 2.00
2 2.60 2.60
3 3.20 3.20
4 3.80 3.80
5 4.40 3.80 incremental error
6 5.00 4.40
7 5.60 5.00
8 6.20 5.60
9 6.80 5.60 incremental error
10 7.40 6.20
11 8.00 6.80
12 8.60 7.40
13 9.20 7.40 incremental error

I have one shipping zone with one class.

Any experiences of this and any fixes.

Thanks
Steven

Hi Steven,

I'm not sure why you have your shipping set to charge by weights when you want to charge for extra quantities.

I would set the 'Calculation Basis' to 'Total Quantity' and then put the following in the grid:

Quantity.............Cost
1..........................2.00

Then set the excess to 'Increment highest value in table' to 0.60 per 1 (so for every extra product ordered an extra 60p will be added to the shipping charge).
