Some Boots No7 products are on a £7 offer at the moment - eg the Airbrush Away primer / powder range, reduced from £16.50. I'm tempted, just because of the price point. But in recent years I've gone off No7 (especially skincare - the protect and perfect skincare range I just found oily and slimy). What's other people's views of No7 - is there anything you find a must-have?
