Price basis and price table
Shipping fees often have a certain price basis. If you want to base the prices, for example, on the order's total weight, choose kg or g from the price basis menu.
After choosing the price basis, you can fill in the limits and prices in the price table. The first row is the base delivery fee that will be at least charged from the customer.
You can add new rows to the price table by clicking Add row. Into those new rows, you can set other prices. For example, if the products weigh 500 at least grams, the price is, etc...
Fixed shipping fees
If you want to use only one fixed shipping fee, set the price to the first row in the table. Then the price will always be the same no matter what the order weighs or which price basis you have chosen.
