Haunted Mansion t-shirts available?

My wife loves the Haunted Mansion ride and we saw a guy walking around with a hitch-hiking ghosts t-shirt during our last visit to the MK.
Are these shirts available anywhere? Can you buy them at the Haunted Mansion?
Any and all help will be appreciated.

Last year there was a cart in Liberty Square that had an assortment of Haunted Mansion items.
