Not RTFT but am planning a clearout.
I have sort of put a stop to buying stuff but I have lapses.There was a bag of Dr Organics stuff in H&B that had been in the clearance section a while and although I had no need for it, I succumbed. It was like 3 products for the price of the cheapest and they are really nice.
I have probably enough make-up to last the rest of my life. Enough shower gel for the same.
I have used up a lot of the sample sizes and agree with the poster above me, a little sachet of eye cream lasts several days.
Some things do not hang around. It doesn't take long to use up a pot of moisturiser or a tube of toothpaste.
An empty tube of anything usually has loads left in it so I cut them and scrape the contents into a small tub.
Some things go off quickly - mascara gets whiffy within months, some lipsticks too, and some foundations separate.
Some products have surprised me by how good they are. The Boots No 7 stuff has surprised me. Body Shop stuff too. I have seen recommendations for things on S&B and some of them have been bargain finds.
I am finding the finishing stuff a bit of a chore. There are some product that I just don't really like using.
