Packaging now, postage later

Flat Rate Satchels come in small, medium and large in packs of 10 - and we have Flat Rate Boxes available too. Buy online now or pick them up at your local participating Post Office1.

Step 1. Pack

Pack your items using a small, medium or large Flat Rate Satchel.

Step 2. Pay

Pay the flat rate postage and print your label via the online parcel sending solution; or address your satchel and pay at a participating Post Office.

Step 3. Post

Put the label in the display pouch on your satchel and pop it into the post box (red for Parcel Post or yellow for Express Post).

Tip: To send or return parcels any time, day or night, try dropping your Flat Rate Satchels off at a 24/7 Parcel Locker. They're free to use, and you'll have proof of posting as soon as you close the locker door. Simply sign up or log in to MyPost to get started.
