An example of one:

The kind where you want to buy something but you have to have some kind of get together, party, hostess type situation. When I want to buy something, I just want to buy it. There is another merchant I came upon, same deal. They even had it where you can check off what you want and add it to your cart only to find out you can't buy it. Have to call a rep. Found lots of merchants like this. But what they are good for is some ebay. Some of these people go to these things, purchase a lot of stuff and turn around and sell it on ebay. Somebody looking to purchase this stuff don't have many options. You can either get a group together or buy it from ebay. Some nice possibilities affiliate wise, not selling it on ebay (you can do that) but I was thinking more PPC or SEO.
