From Spiffy Stores Knowledge Base

Please note: We are currently developing this article, so it is not yet complete

With Australia Post's new flat rate shipping, the way you set up your shipping may need to change. This tutorial is designed to assist new and existing stores to work out a shipping stragey that will work for using weight-based rates in your store. This will also involve altering the weights of your products to weights that may not quite make sense until you read the entire tutorial.


Using Your Own Packaging

Australia Post still has weight-based rates if you use your own packaging. Costs are below.

3kg to 5kg $18.50 $25.50

Setting weights on your products

The best way to work out what weight to set on a product is to firstly weight it (duh!), but if the product is light but large, you should work out the cubic weight of the product. You will need a ruler or tape measure, and a calculator to do so. The formula that Australia Post uses for cubic weight is below, but you can also work it out on here if you struggle with numbers (like me!).

Height x length x width ÷ 6,000

For example: 50cm X 30cm X 40cm
= 60,000cm3 ÷ 6,000
= 10kg cubic weight


Using Satchel Prepaid Satchels

If you intend on using pre-paid satchels, then you will likely need to ensure that your calculations are correct. Your best bet to do this is to buy one of each of them so you can visually see the sizes and gauge what will fit in them. The weights you se on your products may not be anything like the actual of cubic weight.

Setting weights on your products

The best way to work out what weight to set on a product is to see how many will fit into a satchel. Starting with the small satchel if the product will fit.
