This is being advertised on tv at the moment.
Just fill in form and print off voucher!http://www.smirnoffcola.com
*** No need to fill in whole form. Only needs required fields (asterisked) to be filled plus t&c's to be ticked.
It also seems to let you print more vouchers if you use a different email address and/or different name! ***
ANYOE HAVING PROBLEMS, DONT ANSWER ANY OF THE QUESTIONS, LEAVE THEM ALL AT SELECT. And only fill in the fields marked with a *.
Worked for me using this method.
