I don't think TrenD has a website but you could always get in touch with Disney mail order dept. I had them tyrack down a t-shirt my neice wanted and didn't even know where she saw it and they found and shipped it - no problem.
It will probably be easier for you since you know right where to find it.
Here's how to reach them:
Telephone: 407-363-6200
Fax: 407-352-6369
Email:
wdw.mail.order@disneyworld.com
