Honestly the country is missing what could be a great boost to it's Economy; You have to search in the weirdest places at Barnes and Nobles, and check some of the oddest stores to find anything to even find anything to do with the TARDIS, the Sonic Screwdriver, or even The Doctor. This is a wasted opportunity, check with New York, last year there was a boom in Central Park just from one episode of Doctor Who filming there, people wear shirts like "Don't Blink" "Bow ties are cool" Etc.. and yet have no idea what these even really mean.
In the USA the introduction of more British merchandise may lead to an increase in revenue and increase in science awareness despite cost of importing.
Take this as a joke, a Whovian Request (the word Whovian is in Oxford's dictionary), or food for thought
