Hello, the trouble is that there are many other operators other than Royal Mail, and if your client does not use Royal Mail then there is no API key service available.
Looking at WooCommerce competition like Magento this software does postcodes really really well (such as table rates) even without a 3’d party plugins.
The UK is such a huge market I can’t work out why this has not already been added as standard. I feel that the Woo team has greatly underestimated how many customers they have in the UK market, and taken “that will do attitude”.
If anyone is interested; here are the postcodes where you would expect to see higher than normal prices, these postcodes would be the same for most carriers including Royal Mail.
