BzzAgent send you free products to try from some major companies. These are usually either food or cleaning products but not always, sometimes you can get your hands on real products that you can keep. All they ask in return is that you act as a 'Bzz Agent' by discussing the products with your friends, both on social media and face-to-face.

I know some people to feel a bit awkward doing this so if that's you then BzzAgent probably won't be your cup of tea. If you don't mind discussing with your mates though then it's definitely worth signing up with them.
