You can purchase eBay Branded, or Australia Post branded, satchel labels from the Post Office, or the Australia Post eBay Store. You’ll save by purchasing in bulk online, and delivery for eBay branded packaging is free.
You can also print a postage label to use with your own packaging. We’ll carry through the weight and dimensions you’ve specified in your listings, or you can add this info when you create your label. Make sure you’ve included packaging in these amounts, and pay attention to weight restrictions for satchels.
