Neiman Marcus, page-4

Dont know how accurate it is but there appeared to be 154 items for sale when it first showed up.
72 = 24 of each of the three Activators and the other 72 consisting of 12 of each of the six different shampoos and conditioners. Doesn't seem to be a starter pack actually listed as yet so I have allowed for 10 of those.
Currently 16 items have been sold which is roughly 10% of 154.

Also note it is featuring in the New Arrivals section of the US NM site.
