Im in, earnt £200 this year already. As said, its no extra work for free money (well, discounted money). Was gutted I found it AFTER I joined skyHD Its also good how once you register your card you can even get cashback in various shops without having to do anything. Like 4% at cineworld, did it other day thinking it wouldnt work but sure enough, tracked within 48 hrs.
