So, I was just thinking to myself the other day. When do you guys go out and buy back up bottles. When is a fragrance so special to you that you know you have to have another bottle as back up? This idea came to be as I was smelling my original formulation of Dior Homme Sport and how much I enjoy that scent. Even though its 90% full, I am wondering if I should try to find a back up bottle or just deplete that bottle and buy the reformulated version. The problem is I don't know when that would be. But anyways, enough about me, what are your experiences with back up bottles?

Cheers,
