A bulky parcel, a letter, or perhaps a Special Delivery - whatever you're sending, you no longer have to look up the postal cost in a leaflet. Now you can do it all on-line with the Postal Rates Calculator or for more information visit the Postal tariff section.
You can also find out the postcode of an address through this site, find information about redirection and your nearest post office.
Postal rates can be found on the BFPO page on GOV.UK:

INtouch Mail Service
Imail INtouch provides a free service to deployed personnel, to send or receive mail from an entitled BFPO number. The INtouch system replaced the e-bluey service on 1 April 2017.
INtouch messages are alternatives to Forces Free Air Letters (FFALs), known as ‘blueys’, and are also free to send.
The service allows users to upload letters, photos and documents via the internet, which are then securely printed and sent to their recipient. Full details are at the link below:
