No long forms to fill. Just enter your name, Postcode, DOB and email and get £5 off any purchase over £50 at Comet. You can use one of your junk email accounts. I did not even enter my mobile phone number. Date of Birth format is 6 digits in the registration form so for Christmas day 1980: 25/12/80. You do not have to enter your correct D.O.B if you don't want to either.
