Theme Park Connections is in Orlando and has lots of Disney stuff, large and small, and much that is no longer available. It is big and very full of all kinds of stuff. Everything from buttons to Pirates of the Caribbean movie props. Little name tags to full size popcorn cart used in Magic Kingdom. There is an online store and a location in Orlando.

I have been there and it is a fun visit and you can get some Disney World stuff at any price point.
I have a show times sign for my home theater that was used in Disney World for the Hoop De Do Review.
It is located at 2160 Premier Row, Orlando, FL 32809, and I think it was about 20 to 30 minutes away for Disney World to the north.
