Highly recommend Latest Free Suff App (I may have recommended it to some). I have tested now for more than 5 months. Every day you get a notification of the latest free samples. I do not do surveys but applied for some, and they come through like Lancome, Parada Perfume and others. I have put a screenshot of the makeup category. It is on iPhone and Android. YOu may need to test samples before buying large sizes. SephoraUK advertised for 2 weeks to join the community to test samples (Thumb up
@Sephora Team). Mainly all beauty and skincare sold here on SephoraUK. There may be a delay in delivery but will turn up eventually or the advertised brand company will tell you that there is no samples or deals left
