  • Fillz is not responsible for misprinted postage. Print test postage and review the postage file before printing real postage.
  • The weights Fillz offers are estimates (from Amazon and marked up by a percentage to cover packaging). If you don’t want to use estimated weights for items, you can turn this feature of under Postage Settings on the Accounts page of your Fillz account.
  • The weights that appear are for a single copy. If you have two copies of an item, you will need to manually double the weight you see on the postage page.
