I want to do it like this.
a. List items on ebay.
b. Freight to be calculated using a the interparcel calculator.
c. My programmers pull the weight, length, width, breath of the item, and plug it into a bit of code that create the calculator, and then puts the calculator onto the product detail using html.
But your plugin insists I choose a freight option... even though ebay lets me list without a freight option eg
Any way around this?
