This is something DVC and Disney really drops the ball on. I asked this same question right after we purchased and I cannot tell you how many times I've seen it asked since on these boards.
It's ridiculous that they don't make an effort to make this stuff available online and that there's not more available in the shops when you're there. It would be easy money for them and it's free advertising too.
We got free ball caps when we went to Welcome Home Wednesday when we were there a couple of weeks ago. Nothing in the shops intrigued us.
