Reach out to their merchandise services. Their email address is on the UO site somewhere (sorry, I’m on my phone otherwise I’d get it for you). They’ll help you with this. They’ve always been very good with me when buying my T2-related items.
It usually takes them a few days to reply as they surely have several emails ahead to reply to....and when locating merchandise in the parks, they have to reach out to and wait for replies from those particular shops. You may even want to try by phone as you could get faster replies.
