Teresa,
I
think, Monoprix has its own labels for perfumes and many other products, too.
I very much doubt, they are sold anywhere else than at that department store.
Maybe, its web page says something. I doubt however, they ship to the US or even allow to buy online. They have their catalogues sent to customers. I believe you then order by mail (exclusively in France, I believe).
Don't forget, it's sort of budget store, but very good for certain items.

need to go back to Paris anyway... for your hair cut!
