Go to a local bank and get a money order then if you want the cash, and if its something you really want. I had one before my parents knew and it was a pain in the ass taking it off and on, so it was well worth it to tell them
Hmm... Furry convention is definitely the only time I'd wear one. Even then, it's a maybe.

I think I will look like a gay biker or a slave in a BDSM relationship if I will wear a collar. Then I'd be gay biker emo and choke myself while making animal noises in a furry convention while being tied to a tree and raped by a dom.
Some people are in need for that kinds of relationships for some reasons.
