Satchel pricing is offered if the Product you are trying to ship fits into the Satchel.
You may be only able to fit a couple of items into your Satchel, depending on the size of your products.
The packing algorithm will move up to the next size Satchel, assessing the products dimensions and weight permitting.
Remember the first stage of the packing algorithm is to assess the product / products dimensions and then evaluate the volume.
If our Packing algorithm selects a custom box for the packing a Satchel price will not be available at the checkout.
