Good question. I was wondering the same thing. There are some DVC items on eBay. However, I'd prefer a more comprehensive selection, and I'm more concerned with items available now like a DVC T-shirt rather than a collectible like a DVC cast member pin from 1995.
We, too, have been searching for DVC merchandise. Sure seems like Disney is missing the boat on providing a decent selection! Cheeez, if we're willing to pay good money to "own" a piece of the magic, you'd think they would rush to help us advertise the fact! Has anyone written to Disney to suggest more DVC stuff?
I think if you go to those DVC member meetings they play trivia games and give you free merchandise with DVC logos on it.Last Feb.I was on a disney cruise ad they had a get together with members.I went out of curiosity and ended up with DVC picture albums,water bottles,pens,lanyards ,and a DVC baseball cap for me and my kids.
