Fix the lower and upper limits of the range you are creating. Depending on the "Billing" choice, it will display either "Will be applied when the price is" or "Will be applied when the weight is" for the lower limit, and either "Will be applied when the price is" or "Will be applied when the weight is" for the upper limit.
Note that the lower limit is inclusive (>=) whereas the upper limit is exclusive (<). This means that a range's upper limit cannot can have the same value as the next range's lower value, as the two will not overlap.
- Fill in the prices. As soon as both lower and upper limits are filled, PrestaShop makes the "All" field available to edit. This is a special field: any value you enter in it will be copied into the field for all the available geographical zones, without any action on your part. To edit it, tick the checkbox then enter your value. You can then edit the values of each zone field separately.
Check the checkbox for each zone the carrier delivers to at this range. If this carrier does not make deliveries in a given geographical zone for this current range, make sure to uncheck its checkbox.
- Create the range. To create another range, click the "Add new range" button. PrestaShop will add a new column of zone fields. Start again by fixing the lower and upper limits of this range, then filling the prices per zone.
