User Guide
Right from the Shipping page, you can set some first options.
Handling: Enter the handling expenses, and the price or weight
after which your customers receive free shipping. A message will
appear to your customers indicating how much more money they
need to spend in order to receive free shipping. If you don‘t want
this message to appear, type 0 into the fields.
Billing: Choose whether you are calculating the shipping costs by
total weight or price.
The fees section enables you to see the shipping fee for each of the
carriers added to your store.
Carriers
You must have carriers added to your store – that is, a clear indicator of
who will deliver the product. It might be just yourself or your shop (for
instance if you are selling downloadable files, or work locally), but as soon
as you are actually send packages using stamps and a 3rd-party delivery
service (be it your country's national postal service), or FedEx, UPS and
such, then you must have their details added to your store's database.
This will enable you and your customers to better choose which carrier to
use, based on their ranges, fees and such.
