When you have completed a trade via Trendsales and have a Danish home address, you will be able to buy package postage directly from your Trendsales Account.
In order to buy postage, go to My Account / TSpay / As a seller / Completed TSpay, or go to My Account / Buy package label. Then simply enter the package size and weight, and specify which freight company shipping method you wish to ship your item via.
Once you have selected a freight company, and a shipping method, go to payment and complete your purchase. You will then receive an e-mail with your package label or postal code which you attach or write on your package.
