USPS Media Mail Option

-- url of the page with the problem -- : www.leadershipprofilesofcourage.com/Test
-- HikaShop version -- : 2.2.1
-- Joomla version -- : 2.5
-- PHP version -- : x.x.x
-- Browser(s) name and version -- : XXXXX x.x.x
-- Error-message(debug-mod must be tuned on) -- : Error_message

I am using the USPS shipping method but do not see Media Mail. Is there an easy way to add this option or can someone let me know how to go about this?

Any help is much appreciated.
