I have a specific problem, which is that I need to set up some tare functionality but this time with set dollar amounts instead of a percentage. This is because the items in the cart may be less expensive, yet heavy. So a set $ amount will prevent problems.

Can anyone out there help me? I need the following weight in pounds/ hard dollar amounts for handling fees:

1 - 15# $6.00 Handling

16 - 30# $8.00

31 - 50# 10.00

51 - 75# 15.00

76 - 90# 20.00

Is there an add-on that will do this? Has anyone developed this before?
