Well, do you know of an online site that ships the 15mls to Europe? I've searched and searched, but haven't found one.
I was actually considering the small oil rollerball version, it's 7 or 8 ml, I forget now.
Body creams are not for me, I put some on once a month maybe, probably even rarer.
Have you tried Selfridges?
I agree spending a little more for a 50ml spray might be worth it. Even if the smell is exactly the same, I always seem to get better diffusion and performance from a spray.
