When DirtyDog sold WTW at the beginning of 2012 the WTW logo-gear became no longer available. I don't know why that was so...unless DD couldn't legally -- on his own -- sell stuff with "Wander The West" on it after he sold the site...and/or DD didn't want to give permission to the new owners of WTW to continue the offerings.
I'm totally just speculating on the reasons why (beyond the fact of DD selling WTW), but since those who know haven't explained why...
Maybe some members who have such highly desirable items might offer them to the highest bidder, like on Ebay.
I have a couple of extra WTW T-shirts, but I'm saving them as a hedge against stock-market collapse, to provide me a back-up retirement nest egg.
