hi @Jed-RedFrog ,
when using Shopify with the basic plan, your primary option is to set up weight-based flat rates for shipping.
Unfortunately, it may not be feasible to configure precise shipping rates for all regions due to the extensive Royal Mail rate chart, which makes it challenging to use Shopify’s weight-based system accurately. However, you can establish approximate rates based on weight and various regions.
You may also consider using either the actual weight or the dimensional weight, whichever is higher, as the product weight, although this may not provide perfectly accurate rate estimates.
Lastly, if feasible, you could adjust the product price to account for potential shipping losses.
