what is the most concentrated soap?

My kids were in Rome a couple months ago. I, of course, asked them to keep an eye out for shaving shops. I even sent them links and addresses. So, they stumbled across the Santa Maria Novella store and they start texting me if this was OK. I replied, "jackpot". They started telling me the prices so I asked them to text me pics, which they did. They said the sales staff thought they were crazy. Little did they know it is me who is crazy! Amazing prices over there. About half of what is charged here. So, with each pic, I said, OK, one of those, two of those, etc. BTW, another awesome soft Italian soap! Right up there with MdC and Aqua di Parma. FYI, SMN has been making soap since the 1200's! I think they finally got it right. So, when they got home, they tell me they also passed the Aqua di Parma store and I say OMG, why didn't you tell me. They felt bad and got me some for my birthday. Moral of the story, have your sis send pics!
