I am trying to buy a bottle of Eau Sauvage by Dior (not the black bottle, this one)

I normally shave once a week, on a Sunday. I have 7 aftershaves wearing the same one each day and today is Sauvage day. What I cannot quite get my mind around, is the difference in price between the 3 variants, accepting that the dearer ones are more concentrated.
Does anyone have any thoughts they would like to share before I buy the cheapest one!
