Australia Post Calculator , 4 reviews

This POINTLESS app should not be available on Shopify. SHOPIFY, PLEASE CULL. It's causing your guru's and the rest of us business builder's grief. It requires the "carrier-calculated shipping feature option" installed. This is not an app to search for, but something your guru can add to the account for $15/mth. Then you still have problems. TIP: DOWNLOAD THE dinky di, true blue, fair dinkum Australia Post Shipping Extension app and stay away from this lemon. Happy days!

Basically installed the app. No way of getting it working.
Got my My Shopify expert to look at it and same problem. Then attempted to contact via support contact page, still no reply from app developer.
Not recommended at all unfortunately. In summary, "Buyer beware !"
