The WooCommerce Royal Mail shipping extension allows you to offer Royal Mail shipping rates to customers without the need for an API, as Royal Mail does not provide a public API.
To use this extension, your store must use GBP currency and have the United Kingdom as the base country, and your products need to be set up with weights and shipping dimensions.
This extension primarily works with
g, but other units are converted automatically!
This extension supports all the UK and international sending services offered by Royal Mail and Parcelforce in the current Post Office and Online price guides.
