Jaime how old is your DD? Mine is 14. She likes the Elemis gentle foaming face wash (course she does, it was mine!) so I get it cheaper on eBay. I gave her a Mac concealer that was too light for me and she told me yesterday that it was almost out.....I've told her I'll take her to Superdrug for a new one 
Imagine Charlotte getting her mitts on Kate's make up bag! My youngest DS got hold of mine once (it was on top of a tall chest of drawers) and had a whale of a time applying everything and anything. My DH helpfully asked me "why did you let him have it?" like I'd given it to him and said "here you go lad, this will keep you busy for a bit!"
