P160 was all YKW hype, it's a decent soap, but you're quite right, no better than Cella or any other quality product and there's still plenty to choose from.
It only attained magical and mystic properties the moment it was announced it was being discontinued, and the frenzied 'hoarding' started. The news spread to other sites too, and the Chinese Whispers of the fabled P160 was complete. Unsurprisingly, when the buying frenzy wore off, and many missed out, All those 'precious' stocks found their way onto the BB buy sell forums for massively inflated prices. Gentlemen my fkin arse.
The same thing happened with Cade. Someone started a rumour, that it was discontinued, just because their local store didn't have stock in. Despite being denied by Cade HO in France and posted on the same thread (yes, someone emailed them), the shill, buy, and sell wagon started up...
Skin food never impressed me, but MB kept sending samples, so I kept using it and it grew on me. I too found it a bit tacky, but it's a product to use sparingly. Just a biggish pea sized amount will spread and dry smooth.
