Don't know if this has been posted before but I couldn't find it on here so hope this helps someone. Clicks Research send you free products to try out in return for your feedback. I've been with them for about 4 months and so far I've had nutritional supplements, loads of washing up liquid and today I've just received some shampoo and conditioner. They work with some major brands so the stuff you get is usually good quality and the questionnaires only take a few minutes to complete. Nice site if you like your freebies. Just register your details and they alert you whenever there's a relevant study to take part in.
