The other day on QVC Facebook a woman asking about Bareminerals, when told they no longer sell it the usual, but I can't get it.

I was chatting with someone last weekend about cosmetics and QVC, she works in a cosmetic shop and I have heard the same over the years. Brands go to QVC to get exposure and get the brand name out there, or launch in the UK if a US brand. Time passes, they no longer need QVC or decide they no longer want to stick with QVC rules 60 day MBG or perhaps cannot supply the amount of products for shows.
Yes, certain brands just stay Elemis, Gatineau, L'Occitane for years.
