The Flip Of A Coin
Back in 2013, Papa John’s had a promo for the Super Bowl where if you called the coin toss correctly, you would get a voucher for a free one-topping pizza. However, the only control in place was you could only enter the contest one time per email address. I knew exactly what I had to do.
I created more than 60 emails, half of them calling heads, half tails. I ate free for six weeks.
