The Pepsi/iTunes promotion is a great idea and it’s got me hooked. I had given up drinking any kind of soda in lieu of water years ago. But the Pepsi/iTunes promotion has me hooked – I am now going out of my way to buy Diet Pepsi’s to win the free songs on iTunes. So far, I’ve gotten 10 out 11 winners using the MacMerc method of spotting a winner. I’ve gotten quite a few weird looks at the store for going through bottles of Pepsi looking for winners.
