completed the survey with 164 people leaving their email address for the competition. The random number generator chose 162 - the third person to answer the survey! Congratulations to email@example.com - I have emailed you to find out which advertiser you would like the $100 gift voucher with.
Many thanks to all who responded. The intriguing results will be your reward! There is a fair bit of data to crunch, combine that will MIFF and it might be a couple of weeks before I post about it. Big love.
