Help, can anyone tell me where I can get.....

Chocolate cups, you know those little chocolate cups that look like an empty peanut butter cup?? I need to bring something to a party I'm going to and I want to make my chocolate mousse. But I want to put it in those little chocolate cups so that I have more and they are bite sized. I can't find them anywhere!!! I live around Westbury if that helps. Please someone tell me where to get them!!!
