General thought is in the WooCommerce Settings Panel > Shipping > AustPost to include an additional line of data that allows someone to enter a BASE PACKAGING RATE similar to a 'handling fee'.

Idea is that we would then be able to enter correct weights into the product page rather than adding the packaging weight to each product. The downside in the current process is that each product has a weight buffer built in to accommodate the packaging...

Having this "Base Packaging Weight" field one would eliminate the excess weight charges being applied when buying multiple items. Especially for those countries charing per 250 grams and that are SO SO SO Expensive like australia.

Just a thought.. would work ideal for me.. not sure if anyone else has the benefit though..
