USPS offers discounted rates on Priority Mail for packages and envelopes that weigh less than 20 pounds and measure less than 0.5 cubic feet in volume.
This feature is included in the Shopify, and Advanced Shopify plans but has been enabled for those using the Basic Shopify plan until January 18th, 2022 as well.
After January 18th 2022, Cubic Pricing will no longer be available to those using the Shopify Basic plan.
If you found this feature resulted in significant savings for your business, you can always contact support who will be happy to assist in changing your plan, or sign in to your Shopify Admin and update your plan as desired.
To learn about Cubic Pricing such as how to determine package eligibility, as well as calculating rates for soft-pack and padded envelopes, and more, check out Cubic Pricing with USPS Priority Mail within the Shopify Help Center.
