Do you have to pay to mail west mercia

I think there may be a bit of confusion here!

West Mercia is not a postal service or a specific mailing system. West Mercia is actually a police force and a geographic area in the West Midlands region of England, UK.

If you're looking to send mail or packages within the UK or internationally, you'll need to use a postal service such as Royal Mail, ParcelForce, or another courier company. The cost of mailing will depend on the weight, size, and destination of the item, as well as the type of service you choose (e.g., first class, second class, tracked, etc.).

To get an estimate of the cost of mailing, you can visit the Royal Mail website or consult with a postal service provider.
