Keep in mind:  Each new selection must be entered on a new line for it to appear correctly.

You may use actual amounts or percentages. You can also modify shipping weight on an attribute by entering the increase or decrease after the price and separated by a comma. Examples below.

Small(-25,-0.25) Decrease price by 25, decrease weight by 0.25
Medium(-10%,+1) Decrease price by 10%, increase weight by 1
Large(0,+2) Price will remain the same, increase weight 2
