Dispatch timeframes

We aim to dispatch most orders within 1-2 business days of receiving your order. Some products, like personalised stamps, have a longer dispatch time. Any special dispatch / delivery times will be specified on the product page.

Standard delivery is FREE Australia-wide

The estimated timeframe for standard delivery is 3-10 business days after dispatch. However, please be aware we are currently experiencing significant delays due to the pandemic.

Express Post guarantee suspended

Our Express Post service is still available on certain products and is the prioritised delivery option. However, we can’t guarantee next business day delivery and Express Post parcels could take 5+ days to be delivered on top of dispatch time. See our Coronavirus updates page for more information.

Parcel Locker and Parcel Collect deliveries

If you’ve chosen to have your order sent to a Parcel Locker or Parcel Collect address, you’ll receive an SMS and/or email notifying you when your item is ready to pick up.

International delivery

Not all products are available for international delivery. The delivery time for international orders is typically 10+ business days (excluding any time in customs and delays due to reasons outside of Australia Post’s control). Please be aware we’re experiencing substantial international delays due to the pandemic. For more information on these delays, visit the Coronavirus updates page.

For more information on delivery terms, see our Ts&Cs.


Our returns policy

If there’s a problem with a product you have purchased from our Online Shop, you can return the item within reasonable time after purchase. You can choose between an exchange, repair, replacement or refund.

This includes when a product:

  • is faulty
  • is incorrectly described on our website
  • is different from a sample shown

We don’t offer change-of-mind returns on most of our items, as most of them can’t be resold.
