I think the price really had something to do with it.
Last time the kit didn’t sell out for weeks and I am not even sure if it ever sold out. A month after the launch she mentioned that there still was kits available.
Whether you like or can’t stand CH skincare at 60% off is amazing!
Something else to note, the timing of the kits.
First kit landed in end of 2019, the first winter kit.
Spring kit launched in May 2020, 6-7 months later.
Summer kit launched August 2020, 3 months later.
Autumn kit was October 2020, 2 months after summer kit, with a price hike.
Instead of looking at trends from the Autumn kit, she should have been looking at the Summer kit sales, demand and faults
