it looks like there will be another promotion with pepsi giving away free song codes for itunes. also you can win free ipod mini's every hour. the page had been yanked but is back up now. (i just entered my email for the free notification service) we scored pretty well last year winning over 25 free songs. since i drink pepsi along with other soft drinks it was a good deal.
some areas of the country (the northeast) had lots of pepsi codes, while others did not. but the addition to win an ipod mini makes this contest one to watch. you can check free pepsi itunes songs for more info.
