I know what you mean about the Fiery Pink Pepper. I got what I think is the same set from an independent discounter (same batch references as quoted on the forum for the IW ones) and my first observation was the muddy brown colour of the FPP and that it was virtually odourless. I was very disappointed, even though I did only pay £20 for the box of three, but I will use it - as long as I don’t get a skin reaction, obviously.because of all the controversy , (especially about the Pink Pepper which is a favourite), as I had finished a PP I opened the one yesterday from the IW box with batch made May 2023 (I usually have 3 shower gels on the go and would normally have chosen something else). While the smell wasn't as strong the fragrance was perfectly ok, lathered well, and my skin felt just as soft as usual after showering with MB - for me I can't see the difference between this 18 months old set and the ones that appear elsewhere like TK Max - perhaps I am being dim.
Thankfully as I have far too many body lotions to get through I could swerve this tsv!
