Right, it is a very good deal to get the M&S Vouchers and £80 Quidco cash back! Snap it up!
Only issue is, you have to (I had to) wait 6 months before I got my cash back into my Quidco account then had to wait a further 11 days before it was in my account minus £5 which Quidco took.
Other than that you have to wait half a year for your £80 it is the best deal I found on line or via the phone to SKY, they could not match nor beat this offer!!!!
