You can get real-time rates for items using API. With price calculator, you get real-time postage rates for domestic, as well as international shipping. Real-time rates are calculated based on product dimensions and weight, and the best-fitted box rates are returned from Australia Post. This rates will depend on the method used for packing the parcel. Our WooCommerce Australia Post plugin offers three types of parcel packing methods.
They are as shown below.
1. Individual Packing
In this option, each item in the cart is packed separately. Total shipping cost is calculated by adding the shipping cost of each item. This option is selected by default.
For example, the shipping cost of Item X is $10. If the customer adds two quantities of Item X to the cart, the total shipping cost is $10 x 2, which is $20.
2. Pack into boxes with weight and dimensions
If packing items individually does not suit your business, then you can define custom box sizes under Box Dimensions section. All the cart items are packed into custom boxes defined in Box Dimensions settings. The best fit box is automatically chosen from the defined boxes. This is the recommended option. You can read through setting up box dimensions to understand box packing in detail.
The settings are as shown in the screenshot below.
Packing Algorithm: You can pack items in following two ways –
- Volume Based Packing – With this algorithm, the items are placed in the box based on the total volume of both items and the box they are packed into.
- Stack First Packing – Using this algorithm, items are stacked or pilled unto one another, based on either length, width or height of items as well as the box they are packed into.
To know more about this algorithm, read what is stack first algorithm?
Box Dimensions: This setting is applicable only when Pack into boxes with weight and dimension is selected. Here, you can define the outer and inner dimensions of boxes. Outer dimensions are the dimensions of the package. Inner dimensions are the dimensions of the product.
For heavy packing box, enter the weight of the box so that it is added to product weight, to calculate shipping rates. You can tick the respective Letter checkbox if you want to mail letters. Based on your requirement, you can add or remove box dimensions.
Tick the Enable check box of the respective boxes to enable or activate them. If these checkboxes are unchecked, you will not be able to use the selected box(es).
3. Order Total Weight:
Enter maximum weight limit for packages. In this option, the weight of all the cart item is summed up and items are packed with maximum weight limit in the box(es) and passed to API to get rates. In addition to this, you can specify the process of packing, that is, you can pack heavier items first, pack lighter items first or pack items purely divided by weight.
Below is a screenshot showing the order total weight settings.
Stamps.com settings at the Product level
Different products might need a different level of processing. Hence, our plugin provides three important product level settings for stamps.com shipping as shown below.
- HS Tariff Number (Stamps): HS is a standardized system of names and numbers to classify products. Shop owners can provide HS number of the product so that international shipments are processed smoothly.
- Country of manufacture (Stamps): Enter the country code where the product is manufactured.
- Stamps Delivery Signature: If you are selling products that are targeted to adults, or want signatures when deliveries are made, select one of the following options:
- Delivery Confirmation: The US Postal Service can tell you the date, time and zip code where your item was delivered, giving you peace of mind. If the postal carrier tries to attempt a delivery, you’ll get the date and time of that attempt, too. This service is now called as USPS Tracking.
- Signature Required: In this service, the item can be delivered only after obtaining a signature.
- Signature Confirmation: In this service, a signature is required from the recipients of their packages. Although USPS Tracking proves that a package was delivered to a particular address, Signature Confirmation proves that it was actually received by the intended recipient or his agent.
- Adult Signature Required: This service requires the signature of someone who is 21 years of age or older at the recipient’s address.
- Adult Signature Restricted Delivery: This service requires the signature of a specific addressee (or authorized agent), who must be 21 years of age or older.
- None: To completely disable delivery signature option.
Once all the plugin settings are configured and saved, you can move to the front-end of your WooCommerce store to see the affected changes.
