This isn't a competition or really a bargain, more like generaly knoledge.
I signed up to the mars panel a long time ago, I occasionally get asked to test out products of theirs and for this I get sent vouchers (always a higher value than the product in question) then shortly after I am asked to fill out a survey.
I love doing it anyway, the cashiers always seem a bit jealous when I tell them I am a product tester, but to my surprise I just won a £30 Amazon voucher too!
Anyway here is the site and they seem open for registrations!
