Wounded Warriors (which I've checked out) is a legitimate website and an excellent charity. Regardless of how one feels about the war, the victims deserve all of our compassion and support. However, I'd rather donate to them directly than through purchases from a commercial site. Like Keith, I'd prefer to assume that the original post is a case of enthusiasm rather than exploitation. I certainly hope so!
