What are some free samples?

Does anyone know any website that have free samples, by the way im a girl.
So far i've got 2 free samples of twinings tea
And a l'oreal cc cream and bb cream sample

does anyone know any other websites that are giving away free samples?
Update: p.s i'm from the uk so i don't want samples that only work in the US the sample list the first person came up was great but it was only for people in the US.
