I was never tempted by them on QVC (find the guest very annoying and the prices too expensive) but I did pick up a palette in TK Maxx for about £7 and I have to say I really like it! It's the Eyes, Lips & Cheeks palette, the eyeshadows are lovely and soft and very pigmented, the blush is a lovely pink and the lip colours are sheer and feel lovely on. I also have one of the light up lipglosses. I love the gloss itself but the light drives me nuts! It's a very blue light and it actually makes it hard to see your lips, it's so bright! I've tried sticking a pin down the hole to break the little bulb but no joy. It would actually put me off buying another one which is a shame as it's really a lovely gloss.
I do think the prices put people off, plus the fact that they are/were one of those companies who tried to get £100 or more out of you to do those cheesy photo shoot things where they tart you up, then rip you off to buy the photos. Certainly when they had a counter in one of the dept stores in London people always gave them a wide berth...
