Sky offering original bundle £20/ month.
£100 prepaid MasterCard
£115 top cash back (potentially) (tracked)
Called them up after 3 days to cancel and they offered half price so £10/ month for a year.
£120 yearly cost -£100 MasterCard = £20 for a years sky. If the cash back comes through as well potential £95 profit. it's my first post so feel free to correct me. Enjoy
