My rates aren't calculating accurately
If you feel the app is not calculating rates accurately, try these things first:
Check that you have deleted Shopify's default rates. See Delete default rates.
It's important all of your items have weights, Check all of your items have weights.
Check your products are in the correct Shipping profiles.
Check your products are set to Physical products, not service or digital products.
Compare the rates you are seeing with Australia Post's current rates on their website.
If none of the above have worked we recommend you contact our support team.
